Use inttypes.h PRI?32 macros in format strings for [u]int32_t args.
This is a modified and cleaned-up version of PR #4619 by @jpcomito:
hb-common.h now expects 'inttypes.h' presence with MSVC exceptions,
defines __STDC_FORMAT_MACROS in there (if not already defined) and
undoes c930ae2 (PR #1974) and 902ab86.
