x86: add pte_set_flags/clear_flags for pte flag manipulation
It's not necessary to deconstruct and reconstruct a pte every time its
flags are being updated. Introduce pte_set_flags and pte_clear_flags
to set and clear flags in a pte. This allows the flag manipulation
code to be inlined, and avoids calls via paravirt-ops.
