Move the nested PTE bit definitions to pmap.h.

Redefine the PG_xx macros that implicitly refer to bits in the x86 PTEs
to now refer to them explicitly.

Allow code that deals with both regular and nested page table entries to be
compiled with a select set of PG_xx macros undefined. This happens because
the PG_xx macros define bits that are located at different positions in
x86 and nested PTEs. The appropriate bitmask will be determined at runtime
depending on the pmap type.
