StandaloneMmPkg/StandaloneMmMemLib: Change max address computation
Currently the standalonemmlibinternal assumes the max physical bits
to be 36 which is causing issues on v8 architectures.
Instead use the MAX_ALLOC_ADDRESS macro to determine the maximum
allowed address rather than recomputing it locally.
