Subject: [PATCH] [Build] tests: fix compilation on older macOS: add
 port_platform.h (to pull in __STDC_FORMAT_MACROS define) (#32159)

Some versions of MacOS (as well as some `glibc`-based platforms) require
`__STDC_FORMAT_MACROS` to be defined prior to including `<cinttypes>` or
`<inttypes.h>`, otherwise build fails with undeclared `PRIdMAX`,
`PRIdPTR` etc.

See note here: https://en.cppreference.com/w/cpp/types/integer

label: (release notes: no)
