libstdc++: Call regex_traits::transform_primary() only when necessary [PR98723]
This is both a performance optimization and a partial fix for PR 98723.
This commit fixes the issue for bracket expressions that do not depend
on the locale's collation facet. Examples:
* Character ranges ([a-z]) when std::regex::collate is not set
* Character classes ([:alnum:])
* Individual characters ([abc])

PR libstdc++/98723
* include/bits/regex_compiler.tcc (_BracketMatcher::_M_apply):
Only use transform_primary when an equivalence set is used.
