UefiCpuPkg/CpuDxe: Update RefreshMemoryAttributesFromMtrr

Old implementation of RefreshMemoryAttributesFromMtrr directly
retrieves the MTRR register content and applies the MTRR cache type
to GCD database following the precedence order defined by SDM.

The code can updated to simply get all the memory cache types for all
memory through newly introduced API With the new introduced API
MtrrGetMemoryAttributesInMtrrSettings.

Benefits:
1. Remove the duplicated logic in CpuDxe driver that handles MTRR
    details.
2. Let the MtrrLib to handle the case when fixed MTRR is absent.
    (Old logic cannot handle the case.)
