UefiCpuPkg/MtrrLib: Remove unnecessary API MtrrGetVariableMtrr()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2849 MtrrGetVariableMtrr() returns all the variable MTRR settings. But in fact MtrrGetAllMtrrs() and MtrrGetMemoryAttributeInVariableMtrr() are used by callers to get the MTRR settings. The former one returns both the fixed and variable MTRR settings. The patch removes the unnecessary API MtrrGetVariableMtrr() to simplify the MtrrLib API. There is no code in edk2 and edk2-platforms repo that calls MtrrGetVariableMtrr().
