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.

It seems like the standalone "PcAtChipsetPkg.dsc" build failed.

The reason seems to be that PcAtChipsetPkg.dsc contains a lib class
resolution like

  LocalApicLib|UefiCpuPkg/Library/BaseXApicLib/BaseXApicLib.inf

but does not contain a UefiCpuLib class resolution.

Speaking more generally, the following DSC files reference at least one
of "BaseXApicLib.inf" and "BaseXApicX2ApicLib.inf":

- edk2:

  IntelFsp2WrapperPkg/IntelFsp2WrapperPkg.dsc
  OvmfPkg/OvmfPkgIa32.dsc
  OvmfPkg/OvmfPkgIa32X64.dsc
  OvmfPkg/OvmfPkgX64.dsc
  OvmfPkg/OvmfXen.dsc
  PcAtChipsetPkg/PcAtChipsetPkg.dsc
  SourceLevelDebugPkg/SourceLevelDebugPkg.dsc
  UefiCpuPkg/UefiCpuPkg.dsc
  UefiPayloadPkg/UefiPayloadPkgIa32.dsc
  UefiPayloadPkg/UefiPayloadPkgIa32X64.dsc

- edk2-platforms:

  Platform/Intel/MinPlatformPkg/Include/Dsc/CoreCommonLib.dsc
  Platform/Intel/QuarkPlatformPkg/Quark.dsc
  Platform/Intel/QuarkPlatformPkg/QuarkMin.dsc
  Platform/Intel/Vlv2TbltDevicePkg/PlatformPkgIA32.dsc
  Platform/Intel/Vlv2TbltDevicePkg/PlatformPkgX64.dsc

Among these files, the following ones do *not* already have the

  UefiCpuLib|UefiCpuPkg/Library/BaseUefiCpuLib/BaseUefiCpuLib.inf

lib class resolution:

- edk2:

  PcAtChipsetPkg/PcAtChipsetPkg.dsc           [found by CI]
  SourceLevelDebugPkg/SourceLevelDebugPkg.dsc

- edk2-platforms:

  [none]

Therefore, this patch set is sound, it is just incomplete. We need two
patches *prepended*: one patch that adds the UefiCpuLib resolution to
"PcAtChipsetPkg/PcAtChipsetPkg.dsc", and another that adds the same
resolution to "SourceLevelDebugPkg/SourceLevelDebugPkg.dsc". Then the
current (v2) patches can be included verbatim as patch v3 #3, and patch
v3 #4.

Garrett: you can also invoke a personal CI run -- just submit a
github.com pull request with your v3 patches, before posting them to the
list. You will not be able to set the "push" label on your PR, so the CI
system will auto-close the PR (without merging it). But, it will tell
you the build result (pass or failure).

Thanks!
Laszlo
