  Log Message:
  -----------
  [Clang][C++23][WIP] P2071 Named universal character escapes

! Missing tests, some cleanup still needed.

* Add a function in LLVM to map a name to a codepoint.
This using a try to minimize memory usage,
while allowing fast access.

* Add an utility to regenerate this data.

* Support named escape sequences with an extension warning.
I have not yet dealt with C++23 conformance extension warning,
