RFR: 8360515: PROPERFMTARGS should always use size_t template specialization for unit [v4]

> Hello,
> 
> PROPERFMT is defined as the format string "%zu%s", which expects a size_t as input argument. When used in combination with PROPERFMTARGS, which uses the templated byte_size_in_proper_units, the byte size may not be size_t if the input is some other type.
> 
> To minimize confusion, PROPERFMTARGS should always use the size_t template specilization of byte_size_in_proper_units, to match PROPERFMT. Places that use byte_size_in_proper_units with other types can still use it, but should use their own format strings instead of PROPERFMT.
> 
> ProcSmapsSummary::print_on in memMapPrinter_macosx is the only place that uses PROPERFMTARGS with a type that is not size_t. I have changed those places to use the expanded version of the macro, which uses the templated version of byte_size_in_proper_unit instead.
