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.

ec0e6800bc Fix gltf importer forcing vertex colors on all materials 
The importer already checks if a mesh has vertex colors and enables
vertex colors on the material using it.

Before this fix, GLTF importer would force shader generation to use
vertex colors even if the scene did not have vertex colors at all, or
did not need them; causing inefficient shader and PSO generation.

83f2fce078 Add support for KHR_materials_emissive_strength 
This reads the multiplier for the emission strength from GLTF files.

This is fairly universal and is required for blender's emission value to be imported.

The value is a simple universal multiplier and is unitless.

bc24d01359 gltf: Add GLTFHandleBinary::HANDLE_BINARY_EMBED_AS_UNCOMPRESSED 
This option allows for a safe fallback for embedded gltf textures in cases where VRAM compression is not needed.
Add an is_editor_hint guard around GLTFHandleBinary::HANDLE_BINARY_EXTRACT_TEXTURES, to use EMBED_AS_UNCOMPRESSED by default at runtime.
This provides an option for pixel art to be stored losslessly.
Additionally, respect project importer defaults for texture import settings.
Avoid writing and reimporting extracted textures identical to version on disk.
