Add support for regular expressions (#818)
* implementation

* tests

* maybe fix windows compilation?

* undo change of match_flag_type

* switch to boost regex

* move flags to BRegExp object

* fix tests due to cmake 4 update

* update grammar

* update prettifier

* move flag parsing to BRegExp ctor

* add AST nodes, update instr generation and execution

* copy tests but use regular expression literals

* fix grammar for handling division correctly

* modify return values a bit, update tests
- string.match: make groups hold structs of matched, offset
- string.match: add offset
- string.replace: use a groups array like string.match vs individual arguments

* bundle of changes

- standardize error messages
- add more tests for coverage
- move BRegExp creation to static method:  previous implementation had
  ctor throwing, which was no good inside executor since it didn't have
  a try/catch

* more tests; add OT_REGEXP to basic.em

* move string regex stuff to bregexp and support regex/wregex via std::visit

* maybe fix compilation errors?

* add unicode escape sequence handling

* really maybe fix compilation error?

* fix compiler warnings

* refactor a bit to remove duplicate code

* address discord comments
- just return wstring, no need for vector<wchar_t> method

* Add string.split by string and regexp

* Use Max_Split instead of Limit
This makes it match basic::SplitWords

* add support for empty string delim in SplitWords

* remove duplicate code across string.split and mf_SplitWords

* Squashed commit of the following:
