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.

When the MdeModulePkg gCoreEventIdleGuid event is signaled,
CpuSleep is called.  This will cause the CPU to sleep until
the next interrupt occurs.

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.
