Adds P2L validity map tracking - a bitmap marking all physical LBAs
as containing valid (current) user data or not. A clear bit denotes
the location has no valid data and may be skipped during relocation
or compaction. A set bit means it may have valid data (it's still
necessary to do the necessary comparision against L2P).
