  [libc++][format][1/3] Adds more benchmarks. (#101803)

This patch is the start of a series to improve the speed of std::format,
std::format_to, std::format_to_n, and std::formatted_size.

This is mostly achieved by changing the __output_buffer class. This new
__output_buffer class also makes it easier to implement buffering for
P3107R5 "Permit an efficient implementation of std::print"
