 General: Provide _is_utf8_charset() in compat.php for early use

 #61182 introduced is_utf8_charset() as a way of standardizing checks for
 charset slugs referring to UTF-8. This is called by _mb_strlen() inside of
 compat.php, but is_utf8_charset() is defined in functions.php, which isn't
 loaded early on. Code calling mb_strlen() early on before functions.php
 loads in hosts without the multibyte extension therefore may crash.

 Merges [58763] to the 6.6 branch.

 Props dmsnell, jonsurrell, joemcgill, jorbin.
 Fixes #61680.
