* Remove the "TEST_SUPPORTED" traits.
Terrain unit tests should be usable on all platforms, so they shouldn't need a platform-specific trait to enable/disable.

* Fix a few misc terrain bugs.

* Added implementation for calculating normals.
* Fixed bug where GetHeightSynchronous wasn't stopping at the highest-priority layer.
* Added locks for SurfaceData bus to help ensure we lock our mutexes in the correct order and avoid deadlocks.

* Eliminate extra EBus by simplifying area initialization.
Previously, there was a back-and-forth ebus signal used for the terrain system to find any terrain spawners that were created prior to the terrain system activation. Now it uses the more simple technique of just grabbing all the spawners that are currently hooked up to the spawner ebus.

* Create initial LmbrCentral mocks that other Gems can use.
To help improve mock maintenance over time, this creates mocks in the same Gem as the systems being mocked, instead of the other Gems that need to use mocked systems during testing. This way, the mocks should more easily stay in sync with the interface that they mock out.

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.
