This implements the initial version of the std::formatter class and its
specializations. It also implements the following formatting functions:

- format
- vformat
- format_to
- vformat_to
- format_to_n
- formatted_size

All functions have a char and wchar_t version. The locale overloaded
versions aren't implemented yet. Parsing the format-spec and using the
parsed format-spec hasn't been implemented. The code isn't optimized,
neither for speed, nor for size.

The goal is to have the rudimentary basics working, which can be used as a
basis to improve upon.

Implements parts of:

- P0645 Text Formatting

Depends on D93593 <https://reviews.llvm.org/D93593>
