UefiCpuPkg/MtrrLib: Reduce hardware init when program variable MTRRs
When MtrrSetMemoryAttribute() programs variable MTRRs, it may disable/enable
cache and disable/enable MTRRs several times. This updating tries to do
operation in local variable and does the hardware initialization one time only.
(Sync patch r19158 from main trunk.)
