Allow for two more pmap-specific bits in vm_page pg_flags. Define
PG_PMAPMASK as all the possible pmap-specific bits (similar to the other
PG_fooMASK) to make sure MI code does not need to be updated, the next time
more bits are allocated to greedy pmaps.
No functional change, soon to be used by the (greedy) mips64 pmap.
