textlib._create_default_regexes: Avoid using inline flags
- Replace dots with [\s\S] instead of using (?s).
- Replace ^ with (?:(?<=\n)|\A) and replace $ with (?=\n|\Z) instead of
using (?m).
- Replace characters with a character class containing their uppercase
and lowercase forms instead of using (?i).
- During the rewrite most of the E241 errors were resolved. Fix the few
remaining ones and remove E241 from tox.ini ignore codes.
- Sort _regex_cache entries.
- Remoe score, source, ref, pre, and gallery entries. They will be
created on demand during _get_regexes call.
