Inherit buffer tracking handles rather than recreating on resize (#2330)

Browse source 
This greatly speeds up games that constantly resize buffers, and removes stuttering on games that resize large buffers occasionally:

- Large improvement on Super Mario 3D All-Stars (#1663 needed for best performance)
- Improvement to Hyrule Warriors: AoC, and UE4 games. These games can still stutter due to texture creation/loading.
- Small improvement to other games, potential 1-frame stutters avoided.

`ForceSynchronizeMemory`, which was added with POWER, is no longer needed. Some tests have been added for the MultiRegionHandle.
