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

This is the initial Terrain Gem. In this PR, it doesn't do anything, but it contains all of the initial code, icons, and build scripts for the gem to compile and build successfully. The follow-up PR will contain the first round of functioning code.
Also, with the creation of the gem, the TerrainSurfaceDataSystemComponent is getting relocated from the SurfaceData Gem to the Terrain Gem. This should have no impact, as that component has provided no active functionality in o3de. (It will start working again with the initial terrain system code in the next PR)
This also adds a couple of null guards to prefab code to prevent AP crashes, and fixed an incorrect service dependency in the VegetationSystemComponent that was exposed by moving the TerrainSurfaceDataSystemComponent.
