* Making terrain query resolution a single float instead of a Vector2
Signed-off-by: Ken Pruiksma <pruiksma@amazon.com>
* Keeping the concept of different x/y step sizes in region queries since that may be useful and is separate from query resolution. Also keeping the concept of different x/y step sizes in physics since that's independent of the terrain gem.

* Add a ray cast API to the terrain system, implement it, and use it so entities can be placed on top of terrain.
Still to do:
- Unit tests
- Profiling/benchmarks
- Optimization (if needed, may not be now after updating to use the iterative approach, but one option could be to use SIMD to ray cast against both triangles at once)

The "Use Ground Plane" toggle is now functional. When disabled, the terrain layer spawner will say "terrain exists = false" for any point in its bounds unless there's also a Terrain Height Gradient List component with a valid entry. When enabled, it will always say "terrain exists = true", and it will return the min height of the spawner box as the ground plane if there's no valid Terrain Height Gradient List height provider.

* Fix notifications for surface data changes.
Separated the notifications from the surface component and the height component to add a reason to a RefreshArea request. This makes it possible to distinguish between surface changes and height changes and provide the appropriate OnTerrainDataChanged flags.

* Fixed up failing terrain unit tests.
Added API changes, and changed the assumption on where the surface weight sort is taking place. The component is no longer expected to provide the sorted list, it only needs to be sorted at the end coming out of the terrain system, so the unit tests have been modified to reflect that.

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
