Subject: StandaloneMmPkg: StandaloneMmCoreMemoryAllocationLib: Fix compiler
 warning

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.
