* 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.
* Change Activate/Deactivate to happen immediately instead of deferring. There were too many order-of-operation bugs caused by trying to defer this.
* 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.

* Add trivial TerrainSystem tests.
Tests construction, Activate(), Deactivate(), and destruction.

* Unified Terrain system calls on single bus.

* Added mock for TerrainDataNotificationBus listener.
Also added unit tests to verify the listener, and added in missing notification events.

* Removed extra Sampler class.
Fixed up APIs to correctly pass Sampler and terrainExistsPtr around.

* Switched MockTerrainSystem to be proper gmock.
This makes it for flexible to use and easier to reuse from other test environments.

* Fix settings bug caused by bad order of operations that occurred when the methods moved to a different bus.

* 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.

* Switch to NiceMock so that "uninteresting" mock calls get ignored.

* Addressed PR feedback.
Filled in terrainExistsPtr at the end, and added it to GetNormal as well.

* Fixed shader height calculation.
It was off by half a pixel, and it was interpolating, both of which were wrong.

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
