Kernel: Make MemoryManager API type-safe for Region::Access enum

Browse source 
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.
