vanjeff 91ec78241c 1. Introduce the API MtrrGetDefaultMemoryType () in Mtrr Library.
2. Invoke MtrrGetDefaultMemoryType() to get the default memory type instead of the hard code value in module.
3. Add go though for UC attributes.

jljusten 323940278e UefiCpuPkg/CpuDxe: Put CPU to sleep during Idle events
When the MdeModulePkg gCoreEventIdleGuid event is signaled,
CpuSleep is called.  This will cause the CPU to sleep until
the next interrupt occurs.

rsun3 4ec21e8b50 Per PI 1.2 errata B spec, for SetMemoryAttributes() service of CPU Architecture Protocol, EFI_INVALID_PARAMETER should be returned for cases:
If Attributes specifies a combination of memory attributes that cannot be set together, then EFI_INVALID_PARAMETER is returned. For example, if both EFI_MEMORY_UC and EFI_MEMORY_WT are set.

If DEBUG_PROPERTY_DEBUG_CODE_ENABLED is also set in PcdDebugPropertyMask, then the entire set of MTRRs will be displayed on every memory cache setting change.

jljusten 557b970a2f UefiCpuPkg CpuDxe: Fix bug with CPU Arch RegisterInterruptHandler
The change in r10765 introduced an issue where inherited interrupt
handlers would override the driver's RegisterInterruptHandler
functionality.

DUET installs a IDT with 256 entries early in it's boot.  Therefore,
no interrupt handlers could be installed with DUET while using
UefiCpuPkg/CpuDxe (instead of DuetPkg/CpuDxe).

This change forces the IDT to be modified when RegisterInterruptHandler
is called to ensure the UEFI handler will be installed properly.
