KVM: x86/mmu: rename and clarify BYTE_MASK
The BYTE_MASK macro is the central point of the black magic
in update_permission_bitmask(). Rename it to something
that relates to how it is used, and add a comment explaining
how it works.
Using shifts instead of powers of two was actually suggested by
David Hildenbrand back in 2017 for clarity[1] but I evidently
forgot his suggestion when applying to kvm.git.
