03c83cea1e Style: Enable clang-format's InsertBraces config 
This was part of our style guide since we started using clang-format
but the feature was only added in clang-format 15, and we hadn't
noticed it yet.

7bc11b5fe8 Exposure emulated *Unorm4x8 glsl functions in non-android builds

f33ffd9ab4 Add Skeletons and Blend Shapes to the OpenGL renderer 
This uses a similar multipass approach to blend shapes
as Godot 3.x, the major difference here is that we
need to convert the normals and tangents to octahedral
for rendering.

Skeletons work the same as the Vulkan renderer except the bones
are stored in a texture as they were in 3.x.

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.

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!
