StandaloneMmPkg: StandaloneMmCoreMemoryAllocationLib: Fix compiler wa…

…rning Assigning MmramRangeCount from MmCorePrivate (UINT64) to local variable MmramRangeCount (UINT32) will cause compilation failure due to "warning C4244: '=': conversion from 'UINT64' to 'UINT32', possible loss of data". This changes defines local MmramRangeCount as UINTN type and adds type cast before value assignment.
