Ryan Houdek 5514a04cb4 Utils/64BitAllocator: Minor cleanups and optimization for munmap ...

- Some minor cleanups in the VMARegion struct type.
- Switches over to using the FlexBitSet range scanning, based off this
implementation.
- Move memory region allocation to its own function instead of
  constructor
  - This will be used by a new constructor later for 48-bit host-side
    allocations
- Minor optimization to keep track of Munmap.
  - We were burning a bunch of time on backward scanning for free
    regions even though we never did a munmap to free anything.
  - Now only do backward scanning if a munmap occured.
  - Saves a bunch of CPU time
