57eb762bae Add option to enable HDR rendering in 2D 
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance

Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.

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.

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

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.

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