Kernel: Make MemoryManager API type-safe for Region::Access enum
Increase type-safety moving the MemoryManager APIs which take a Region::Access to actually use that type instead of a `u8`. Eventually the actually m_access can be moved there as well, but I hit some weird bug where it wasn't using the correct operators in `set_access_bit(..)` even though it's declared (and tested). Something to fix-up later.
