  Log Message:
  -----------
  [libc++][format] Adds string formatter.

Implements the formatter for all string types.
[format.formatter.spec]/2.2
For each charT, the string type specializations
```
  template<> struct formatter<charT*, charT>;
  template<> struct formatter<const charT*, charT>;
  template<size_t N> struct formatter<const charT[N], charT>;
  template<class traits, class Allocator>
    struct formatter<basic_string<charT, traits, Allocator>, charT>;
  template<class traits>
    struct formatter<basic_string_view<charT, traits>, charT>;
```
This removes the stub implemented in D96664.

Implements parts of:
- P0645 Text Formatting
- P1868 width: clarifying units of width and precision in std::format
