UefiCpuPkg/MtrrLib: Refine the debug messages
UefiCpuPkg/MtrrLib: Refine the debug messages

MtrrSetMemoryAttributesInMtrrSettings() missed the debug messages
of memory attribute request and status. The patch moves all debug
messages from MtrrSetMemoryAttributeInMtrrSettings() to
MtrrSetMemoryAttributesInMtrrSettings() and refines the debug message
to carry more information.
