StandaloneMmPkg/StandaloneMmCore: Fix compiler warning

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3204

Fixes the following compiler warning in VS2019 by changing defining
the MmramRangeCount variable to be UINTN and type casting prior
to value assignment.

\edk2\StandaloneMmPkg\Core\StandaloneMmCore.c(570): error C2220:
  the following warning is treated as an error
\edk2\StandaloneMmPkg\Core\StandaloneMmCore.c(570): warning C4244:
  '=': conversion from 'UINT64' to 'UINT32', possible loss of data
