#43224 new enhancement

Extract `$utf8_pcre` from `wp_check_invalid_utf8()` into a separate function

The wp_check_invalid_utf8() function checks to confirm support for the /u flag in regular expressions. The result of that check is cached in a static variable within that function. However, other areas of the codebase might want to run the same check, or maybe plugins would like to check also.

I'm considering a change in Gutenberg's PEG parser and that might serve as an example use case for the new wp_can_utf8_pcre() function I'm proposing in this ticket. Instead of running the same check all over again, having this check run once by a utility function would be nice.

Update: The Gutenberg PEG parser (in PHP) is actually generated by a JavaScript library, so maybe it's not the best example of a use case for this. However, I still think the patch is worth considering.
