154b9c1c91 Use a giant UBO to optimize performance in 2D
This removes the countless small UBO writes we had before
and replaces them with a single large write per render pass.

This results in much faster rendering on low-end devices
but improves speed on all devices.

fea48cdfc6 Fix rendering when using WebGL2.
Fixes include using proper depth buffer format in 3D (this had previously been fixed already but the changes were lost in a rebase), Remove unused lighting and shadowing code in 2D, and update 2D UBOs using glBufferSubData so that they remain the appropriate size.

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.

Add a shadow opacity property to Light3D
This can be used to make shadows translucent for a specific light.

The light distance fade system also uses this to smoothly fade the shadow
when the light fade transition distance is greater than 0.

Use OpenGL 3.3 core profile instead of compatibility profile
- Rename OpenGL to GLES3 in the source code per community feedback.
  - The renderer is still exposed as "OpenGL 3" to the user.
- Hide renderer selection dropdown until OpenGL support is more mature.
  - The renderer can still be changed in the Project Settings or using
    the `--rendering-driver opengl` command line argument.
- Remove commented out exporter code.
- Remove some OpenGL/DisplayServer-related debugging prints.

386968ea97 Remove obsolete GLES3 backend
Due to the port to Vulkan and complete redesign of the rendering backend,
the `drivers/gles3` code is no longer usable in this state and is not
planned to be ported to the new architecture.

The GLES2 backend is kept (while still disabled and non-working) as it
will eventually be ported to serve as the low-end renderer for Godot 4.0.

Some GLES3 features might be selectively ported to the updated GLES2
backend if there's a need for them, and extensions we can use for that.

So long, OpenGL driver bugs!

b835868067 Create shadow_vec for altering shadow computation
In 2.1 and 3.0, light_vec could be modified for altering shadow_computations.
But it broke shadows when rotating light. shadow_vec would do the same, but without breaking
shadows in rotated lights if not used.

Add inverse light transformation to shadow vec, so it's not affected when rotating lights;

Added usage define for shadow vec.

For shadow vec working properly when rotating a light, it's needed to multiply it by light_matrix normalized. Added usage define in order to don't do that if shadow_vec not used.

aa3ef8893b Removed clamping of the Linear tonemapping when KEEP_3D_LINEAR
Changed the behaviour of the Linear tonemapping operator to not clamp to [0, 1] range
in the case when KEEP_3D_LINEAR is defined. This allows to render values > 1.0 in
floating point texture targets (via Viewport) for further processing or saving high
dynamic range data into files. This only works when no color conversion is active.

8fb80788df changed the constant scale of cube_normal to -1.0 instead of -1000000.0; this fixes a rendering issue on oculus quest and does not change the computation as the vector is normalized afterwards.
Adapted the comment above the code to reflect the change made as it already mentioned that z could be set to 1.

02ea99129e Adding a new Camera Server implementation to Godot.
This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server.
Other parts of Godot can interact with this to obtain images from the camera as textures.
This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.

Improve SSAO performance and quality
This decreases the number of samples significantly, leading to a
notable performance increase with only a very slight loss in
visual quality.

This also tweaks the default SSAO settings to use 3×3 blurring,
which makes noise patterns much less visible.
