* Terrain ray cast benchmarks and optimization:
- Added some benchmarks that exercise terrain ray casting.
- Optimized terrain ray casting by removing an unnecessary AABB intersection check (this was suggested by @invertednormal in the original review, but I forgot to actually remove it until now).
- Fixed a bug where we were not normalizing the ray direction before performing the Moller-Trumbore ray<->triangle intersection calculations.

* 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.
