Jian J Wang 0dbb0f1a5c UefiCpuPkg/CpuDxe: fix bad boot performance
If features like memory profile, protection and heap guard are enabled,
a lot of more memory page attributes update actions will happen than
usual. An unnecessary sync of CR0.WP setting among APs will then cause
worse performance in memory allocation action. Removing the calling of
SyncMemoryPageAttributesAp() in function DisableReadOnlyPageWriteProtect
and EnableReadOnlyPageWriteProtect can fix this problem. In DEBUG build
case, the boot performance can be boosted from 11 minute to 6 minute.
