Move check for USE_AVX512_POPCNT_WITH_RUNTIME_CHECK.

Unlike TRY_POPCNT_FAST, which is defined in pg_bitutils.h, this
macro is defined in c.h (via pg_config.h), so we can check for it
earlier and avoid some unnecessary #includes on systems that lack
AVX-512 support.

Oversight in commit f78667bd91.
