Implements [[ https://wg21.link/p2071r1 | P2071 Named Universal Character Escapes ]] - as an extension in all language mode, the patch not warn in c++23 mode will be done later once this paper is plenary approved (in July). We add * A code generator that transforms `UnicodeData.txt` and `NameAliases.txt` to a space efficient data structure that can be queried in `O(NameLength)` * A set of functions in `Unicode.h` to query that data, including * A function to find an exact match of a given Unicode character name * A function to perform a loose (ignoring case, space, underscore, medial hyphen) matching * A function returning the best matching codepoint for a given string per edit distance * Support of `\N{}` escape sequences in String and character Literals, with loose and typos diagnostics/fixits * Support of `\N{}` as UCN with loose matching diagnostics/fixits. Loose matching is considered an error to match closely the semantics of P2071. The generated data contributes to 280kB of data to the binaries. `UnicodeData.txt` and `NameAliases.txt` are not committed to the repository in this patch, and regenerating the data is a manual process.
