Yao, Jiewen 53ba3fb8aa UefiCpuPkg/PiSmmCpu: Always set WP in CR0
So that we can use write-protection for code later.

It is REPOST.
It includes suggestion from Michael Kinney <michael.d.kinney@intel.com>:
- "For IA32 assembly, can we combine into a single OR instruction that
  sets both page enable and WP?"
- "For X64, does it make sense to use single OR instruction instead of 2
  BTS instructions as well?"
