Subject: [PATCH] [libc++][NFC] Disable std_format_spec benchmarks through lit
 instead of the preprocessor (#179228)

This is probably a relic from when we didn't use lit to run benchmarks.
Nowadays we should just use the lit features to disable benchmarks like
we do in any other test instead of using the preprocessor.
