* Terrain feature processor improvements regarding material, mesh, and lod
- Now using a material with pbr lighting for terrain. Removed some of the old shader code that wasn't needed anymore
- Move heightmap image declaration to the material so it's not needed in the object SRG anymore
- Added prototype code (commented out) for smoothing the terrain with a b-spline weighting function
- Mesh data is all made with a proper mesh asset now.
- Added basic LOD support (no continuous LOD yet, but it does pop between lod levels)
- Moved RenderCommon to be accessible publicly. It contains stencil refs that should be public.

The terrain feature processor was crashing due to an invalid shader name. The shader name has been fixed, but the feature processor has also been hardened so that it no longer crashes if a shader fails to load.
Also, while testing, this inadvertently exposed a second crash in EntitySerializer that occurs when components don't serialize in correctly.

* Various terrain improvements:
- Height now stored in a R16_unorm to decrease the amount of memory / memory bandwidth needed for the height field
- Many simplifications to the feature processor
- Added a shader to render to the depth pre pass
- Pulled common functionality needed by depth and forward to a common include shader
- Forward shader now outputs to all the expected render targets
- Adjusted the way normals and lighting are being calculated

This represents the very beginnings of the Terrain System presented in Sig-Content RFC 4 ( https://github.com/o3de/sig-content/blob/main/rfcs/rfc-4-terrain-system.md ). There is some basic working functionality in this PR, but the system as a whole should not be considered working yet. The gem is disabled by default in all projects.
All of the code below is contained in the Terrain Gem, which is disabled by default. The following components exist and can be experimented with, but should not be expected to be functionally complete yet:
Terrain World - level component for enabling terrain
Terrain World Debugger - level component for enabling terrain debugging features
Terrain Layer Spawner - component for defining a region of terrain
Terrain Height Gradient List - component for defining a list of gradients to use as terrain heights
