385ee5c70b Implement Physical Light Units as an optional setting.
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.

In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

2ee77f6f05 GPULightmapper: better algorithm to generate rays for indirect lighting
Previous algorithm used an algorithm to generate rays that was not completely
random. This caused artifacts when large lighmap textures were used.

The new algorithm creates better rays and by that prevents artifacts.

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

5465ef83cb GPULightmapper: execute dilate also after denoise
Dilate fills gaps that are caused by the rasterization. As dilate is based on
the alpha-channel which is not part of denoise, dilate can be run after denoise
as well. So that colors are not denoised/mixed over seams.

a7599076d2 GPULightmapper: execute dilate before denoise
Dilate fills gaps that are caused by the rasterization. Previously denoise
was done before dilate which caused the gaps to become filled (non-zero). This
resulted that the gaps were not recognized by
dilate  and the background color leaked.

This is fixed by executing dilate before denoise.

a3f315c81b GPULightmapper: increase ray triangle hit rate
Currently the method ray_hits_triangle determines triangles not to be hit by
a ray due to an epsilon that is too big. In practice those triangles are hit by
those rays.

This is fixed by introducing a smaller epsilon.

f3f64389ca GPULightmapper: prevent loop with max iterations
In case the calculation of the delta contained infinity values (division by
zero), than later the calculation of the next cell failed as the infinity value
was multiplied by zero which resulted in a nan. The nan-value caused that the
next cell was equal to the current cell which resulted in an end-less loop,
which only terminates by the maximum iterations protection.

This is solved by replacing infinity with grid_size which acts as infinity.

fbd95c3e53 GPULightmapper: process rays to sky in all bounces as active
Before this change only rays to the sky (RAY_MISS) in the first bounce were
processed as active rays. This caused artifacts, areas were too light, when
more than one bounce were processed.

Now rays to the sky are processed as active rays for all bounces.

9e58b02252 GPULightmapper: skip smoothen positions for flat triangles
Smoothening positions for flat, non-smoothened, triangles is unnecessary and
caused positions to move outside their  triangle which caused side-effects as
rays from those positions intersected with triangles which could not be
reached from the original triangle.

This is solved by skipping smoothening of positions for flat triangles.
A triangle is determined to be flas as its vertex normals are equal.

7c19684ee9 GPULightmapper exclude back-face triangles while calculating bounces
Edges that are at the edge of a plane, may get behind the scene and will hit
back-face triangles which where included in the lighting calculations. This
caused leaking of light at the edge of planes.

In case a ray hits back-face triangle, it is skipped in the bounce calculations.

e11dd6500a GPULightmapper's triangles and their bounding box will be in-sync
Previously the bounding boxes and triangles were maintained in two separate
arrays (Vectors). As the triangle vector was sorted and the bounding-box array
was not , the order of both arrays differed. This meant that the index in one
was different than the other, which caused lookup issues.

To prevent this, the bounding-box is now part of the triangle structure so that
there is a single structure that cannot become out-of-sync anymore.

cf3f404d31 Implement Binary Shader Compilation
* Added an extra stage before compiling shader, which is generating a binary blob.
* On Vulkan, this allows caching the SPIRV reflection information, which is expensive to parse.
* On other (future) RenderingDevices, it allows caching converted binary data, such as DXIL or MSL.

This PR makes the shader cache include the reflection information, hence editor startup times are significantly improved.
I tested this well and it appears to work, and I added a lot of consistency checks, but because it includes writing and reading binary information, rare bugs may pop up, so be aware.
There was not much of a choice for storing the reflection information, given shaders can be a lot, take a lot of space and take time to parse.

6995b0429c Assorted fixes to UV unwrapping and GPU lightmapper
Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:

* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
	- Added padding between atlas elements, avoids bleeding.
	- Remove old SDF generation code.
	- Fix baked attenuation for Omni/Spot lights.
	- Fix baking of material properties onto UV2 (wireframe was
	  wrongly used before).
	- Disable statically baked lights for objects that have a
	  lightmap texture to avoid applying the same light twice.
	- Fix lightmap pairing in RendererSceneCull.
	- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
	- Port autoexposure fix for OIDN from 3.x.
	- Save debug textures as EXR when using floating point format.

Inverted the spotlight angle attenuation so a higher value results in

Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

c74d65cec8 GLSL: Change shader type specifier from [vertex] to #[vertex]
The added `#` prevents clang-format from misinterpreting the meaning
of this statement and thus messing up the formatting of the next
lines up until the first `layout` statement.

Similarly, a semicolon is now enforced on `versions` defines to
prevent clang-format from messing up formatting and putting them
all on a single line. Note: In its current state the code will
ignore chained statements on a single line separated by a semicolon.

Also removed some extraneous lines missed in previous style changes
or added by mistake with said changes (e.g. after uniform definitions
that clang-format messes up somewhat too, but we live with it).

07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.
