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.

1e60a0ecfc UefiCpuPkg MTRR Library: enhance MTRR Library.
When it finds that a request range is covered by an existing MTRR with same cache type, the MTRR library set a flag and continues to check other MTRRs and invalidate any MTRR of the same request range with a higher-priority cache type.

f877f3006e Add DEBUG() macros for DEBUG_CACHE to MTRR Library show all changes memory caches setting changes.
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.

2) Change MACRO:
#define  MTRR_NUMBER_OF_VARIABLE_MTRR  32 // the semantics are changed from NUMBER to MAX_NUMBER.
#define  FIRMWARE_VARIABLE_MTRR_NUMBER  6 // wrong and deprecated
#define  MTRR_LIB_IA32_VARIABLE_MTRR_END 0x20F // wrong and deprecated
#define  RESERVED_FIRMWARE_VARIABLE_MTRR_NUMBER  2 // add new one.
