Originally these functions were exposed on all GLSL ES 300 devices. However, that causes a build error as Android devices expose the *Unorm4x8 functions despite them not being in the ES 300 spec

clayjohn 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.

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

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.

Rémi Verschelde 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!

azagaya 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.

Holger Dammertz 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.

Holger Dammertz 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.
