* Add comparison operator for use from unit tests.

* First version of FastNoise benchmarks.

* Simplified unit tests and added initial benchmarks.

* Add GetValue vs GetValues unit test.

* Moved Gradient test code into helper files for use from FastNoise.
Also added benchmarks for each type of FastNoise so that we can have some comparative values handy.

* Change flow so that TerrainSystem stops responding during deactivation.
Some systems might accidentally try to call back to the TerrainSystem inside a DestroyBegin notification, so make sure it stops listening before sending out the notification.

* Change gradients to cache and use a GradientTransform instance.
In my local test case, calling EBus on every call took 337 ms, using a lambda to wrap the calls took 197 ms, and using the fully cached version took 170 ms.

* Remove the wrappingTransform function and go back to the switch statement.
There was a bit of overhead to each function call due to using AZStd::function that just isn't necessary for this use case.

* Add profile markers to the heightfield updates so that they're more visible.

* Cleared state while component is deactivated.
The state was getting refreshed even while the component was in a deactivated state, which meant that it wasn't properly notifying of state changes when it became active since it wasn't detecting an actual change. By clearing the state when deactivated, and ensuring the state isn't getting refreshed *while* deactivated, the notifications work properly.

* First version of GradientTransform class.
The gradient transform logic is getting encapsulated into a class so that it can be cached and used by components in a much more optimal way than making ebus calls to the GradientTransform component on every transformed point.

* Moved GradientTransform into its own source files.

* Clean up and simplify GradientTransform logic.
Added extensive commenting and split TransformPositionToUVW into a separate method for normalizing (TransformPositionToUVWNormalized) so that there doesn't need to be any conditional logic. There's no runtime variance as to which one needs to be called from a given call site.
