* In this case, instead of baking each mesh material property to it's own buffer, we can write all the meshes to the same buffer as their UVs are already the final ones that do not overlap
* Memory usage is greatly reduced (in test case with ~300 materials to bake, peak is reduced by 5.5GB)
* A lot faster to process (~2x in most cases) as we are doing a single RT readback per baked material property
* We can also skip the final merge of the baked outputs, as we have a single one
Refactored the material baking module to have both code paths (single output and multi outputs) share as much code as possible

* If set to true, values stored in the emissive textures will be clamped to the [0, 1] range rather than being normalized and scaled back using the EmissiveScale material static parameter

Also create a FViewFamilyInfo for DrawTileMesh so that we have a valid SceneTexturesConfig when setting up view uniforms.
Moved material baking renderdoc capture so that it captures warm up frames.

Number of warmup frames is controlled by MaterialBaking.VTWarmupFrames CVar and defaults to 5
Warmup should only happen if material samples virtual textures.

Providing a new flatten material with the correct texture samplers.
Retrieve texture properties from the default textures in the material (linear vs srgb, compression, vt enabled, lod group...)
Previously generated material instances are unchanged.
All MergeActor engine tests pass successfully.
