  [libc++] Fix std::regex_search to match $ alone with match_default flag (#78845)

Using std::regex_search with the regex_constant match_default and a
simple regex pattern `$` is expected to match general strings such as
_"a", "ab", "abc"..._ at `[last, last)` positions. But, the current
implementation fails to do so.

Fixes #75042
