Add RenderingServer.get_video_adapter_type() method
This can be used to distinguish between integrated, dedicated, virtual
and software-emulated GPUs. This in turn can be used to automatically
adjust graphics settings, or warn users about features that may run
slowly on their hardware.

c571e4a7f4 Implement distance fade and transparency
The built-in ALPHA in spatial shaders comes pre-set with a per-instance
transparency value. Multiply by it if you want to keep it.

The transparency value of any given GeometryInstance3D is affected by:
   - Its new "transparency" property.
   - Its own visiblity range when the new "visibility_range_fade_mode"
     property is set to "Self".
   - Its parent visibility range when the parent's fade mode is
     set to "Dependencies".

The "Self" mode will fade-out the instance when reaching the visibility
range limits, while the "Dependencies" mode will fade-in its
dependencies.

Per-instance transparency is only implemented in the forward clustered
renderer, support for mobile should be added in the future.

Add Soft Very Low shadow quality mode for 3D
This can be used to improve 3D shadow rendering quality at little
performance cost. Unlike the existing Hard setting which is limited
to variable shadow blur only, it works with both fixed blur and
variable blur.

Allow any floating-point value as a 3D rendering scale option
This allows for finer control over 3D rendering resolution.
Supersampling can also be performed by setting a 3D rendering
resolution above 1.0, which is useful for offline rendering or
for very high-end GPUs.

Remove unimplemented Environment.ambient_light_occlusion_color property
This property was intended to provide a way to have SSAO or VoxelGI
ambient occlusion with a color other than black. However, it was
dropped during the Vulkan renderer development due to the performance
overhead it caused when the feature wasn't used.

9e1810695c Auto LOD fixes and improvements
* Fixed LODs for shadow meshes.
* Added a merging step before simplification. This helps with tesselated
  meshes that were previously left untouched. The angle difference at
  wich edges ar considered "hard" can be tweaked as an import setting.
* LODs will now start with the highest decimation possible and keep
  doubling (approximately) the number of triangles from there. This
  makes sure that very low triangle counts are included when possible.
* Given more weight to normal preservation.
* Modified MeshOptimizer to report distance-based error instead of
  including attributes in the reported metrics.
* Added attribute transference between the original mesh and the
  various LODs. Right now only normals are taken into account,
  but it could be expanded to other attributes in the future.

Remove 16× MSAA support due to driver bugs and low performance
In the `master` branch, 16× MSAA caused the entire system to freeze
on NVIDIA GPUs. This is likely caused by graphics drivers not actually
implementing 16× MSAA, but combining 8× MSAA with 2× SSAA instead.

On top of that, modern shader complexity makes 16× MSAA very difficult
to use while keeping a good framerate. 8× MSAA is hard enough to use
as it is.

* Shadow quality settings now specialization constant.

3a53ae5d9f Implement visibility range and dependencies.
This commit adds the following properties to GeometryInstance3D: `visibility_range_begin`,
`visibility_range_begin_margin`, `visibility_range_end`, `visibility_range_end_margin`.

Together they define a range in which the GeometryInstance3D will be visible from the camera,
taking hysteresis into account for state changes. A begin or end value of 0 will be ignored,
so the visibility range can be open-ended in both directions.

This commit also adds the `visibility_parent` property to 'Node3D'.
Which defines the visibility parents of the node and its subtree (until
another parent is defined).

Visual instances with a visibility parent will only be visible when the parent, and all of its
ancestors recursively, are hidden because they are closer to the camera than their respective
`visibility_range_begin` thresholds.

Combining visibility ranges and visibility parents users can set-up a quick HLOD system
that shows high detail meshes when close (i.e buildings, trees) and merged low detail meshes
for far away groups (i.e. cities, woods).

8b19ffd810 Make Servers truly Thread Safe
-Rendering server now uses a split RID allocate/initialize internally, this allows generating RIDs immediately but initialization to happen later on the proper thread (as rendering APIs generally requiere to call on the right thread).
-RenderingServerWrapMT is no more, multithreading is done in RenderingServerDefault.
-Some functions like texture or mesh creation, when renderer supports it, can register and return immediately (so no waiting for server API to flush, and saving staging and command buffer memory).
-3D physics server changed to be made multithread friendly.
-Added PhysicsServer3DWrapMT to use 3D physics server from multiple threads.

Update copyright statements to 2021
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 🎆

-Fixes #43979 (I needed to test)

WARNING:

-NOT backwards compatible with previous 4.x-devel, will most likely never be, but it will force reimport scenes due to version change.
-NOT backwards compatible with 3.x scenes, this will be eventually re-added.
-Skeletons not working any longer, will fix in next PR.

Add a debanding property to Viewport
It can be enabled in the Project Settings
(`rendering/quality/screen_filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).
It will also slightly brighten the scene's dark areas.

As a result, it should be enabled only when banding is noticeable enough.

This closes #17006.

6a5ecfdef1 Restored fog (non volumetric).
Uses a simpler and more intuitive implementation based on density.
Its less flexible than before, but its easier to get nice results.

0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

Part of #33027.
