Implement `range-default-formatter`

frederick-vs-ja commented 2 weeks ago

Towards #2919/WG21-P2286R8/WG21-P2585R1.

The following tests are derived from libc++'s test files:

Note that libc++'s range_formatter is currently buggy on the m option, see LLVM-90196 and LLVM-94562.

The test P2286R8_text_formatting_tuple_disambiguation covers formatting pairs and tuples that are also ranges.

Unblocks libcxx tests:

~Remaining test failures seem related to #4320. Perhaps I also need to fix it.~

Edit: nope, they're unrelated. The locale-related test cases should be conditionally skipped.

There are a lot of code movements. To make code review easier, can you split them into a separate commit?

Done.

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.
