51ed3aef63 Vertex and attribute compression to reduce the size of the vertex format. 
This allows Godot to automatically compress meshes to save a lot of bandwidth.

In general, this requires no interaction from the user and should result in
no noticable quality loss.

This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.

Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.

7c812cd7e9 Fix use of discard in shaders 
discard was being included in all shaders set to depth pass opaque, which is the majority of shaders

Instead it should only be used with alpha prepass materials

e2321c21db Enable the use of all builtins on the light shader 
When using the light process in spatial shader,
the built-ins work as spected, now they work in forward+,
mobile and compatibility renderer.

8452e6cdb3 Add SPECULAR_AMOUNT spatial light shader built-in 
Light3D has a light_specular property which is used to set the
intensity of specular contributed by this light source, but it was
previously only used by the default material light shader, and not
possible to use in a custom light() shader.

This does not include 3D SDF collisions, trails, or
manual emission.

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!
