Mark de Wever d7444d9f41 [libc++][format] Implement formatters. ... 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. 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. The formatters used in this commit are simple stubs that will be replaced by real formatters in later commits. The formatters that are slated to be replaced in this patch series don't have an availability macro to avoid merge conflicts. Note the formatter for `bool` uses `0` and `1` instead of "false" and "true". This will be fixed when the stub is replaced with a real formatter.
