SurfaceData cleanups to prepare for bulk APIs (#7166)
* Initial cleanup of GetSurfacePointsFromRegion in prep for bulk API support.
* Removed the generated lookup point from the output structure. Nothing was using it, and by keeping it separate, I can pass it in as a list of points that can be passed throughout the terrain, gradient, and surface data APIs.
* Clarified on the SurfaceProvider bus that GetSurfacePoints() only gets valid XY values on the inPosition.
* Simplified the TerrainSurfaceDataSystemComponent implementation a bit.  The EnumerateHandlers() and the terrain Aabb checks were overkill. Also, the terrain Aabb check assumed that the Z value on the inPosition was valid, which it isn't always.

Change gradients to use cached GradientTransform instance (#6591)
* 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.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* 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.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Remove the wrappingTransform function and go back to the switch statement.

* 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.

Optimized Terrain Debugger Wireframe rendering (#6572)
* Optimized wireframe drawing.
As a part of rearranging the code to make use of the upcoming ProcessHeightsFromRegion, the number of calls to GetHeight could be reduced, dropping the refresh time in my test case from 2550 ms to 1068 ms.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Change refresh to only happen on wireframe draws.
This helps ensure that multiple data changes in a single frame don't cause multiple refreshes, and prevents us from taking a refresh penalty when the wireframe isn't being drawn at all.

Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>

* Change debugger to update wireframes incrementally.
This works by having a fixed NxN grid of sectors.  The camera is always considered as being in the center of the grid, so anytime the camera's grid square changes, only a subset of sectors are updated to have the new wireframe data.

* Terrain surface data wasn't updating its AABB correctly.

Mike Balfour 97b0eddcb4 Hook up the "Use Ground Plane" toggle.
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.
