AMD processor does not support MSR_IA32_MISC_ENABLE register. Accessing
this register on AMD causes an unhandled exception in SmmEntry.nasm and
a subsequent failure to boot since this is too early in SMM path for the
exception handler to be loaded.
First, to distinguish between AMD and other processors, refactor
StandardSignatureIsAuthenticAMD into BaseUefiCpuLib. So there is only
one copy in the source. All changed modules already include UefiCpuLib
either directly or indirectly so could not easly split first patch.
Second, Skip manipulation of MSR_IA32_MISC_ENABLE register if running
on an AMD processor.
Tested on AMD X64 hardware.
OvmfIa32 and OvmfIa32X64 on Intel hardware.
