Improve handling of static assert messages. 

Instead of dumping the string literal (which
quotes it and escape every non-ascii symbol),
we can use the content of the string when it is a
8 byte string.

Wide, UTF-8/UTF-16/32 strings are still completely
escaped, until we clarify how these entities should
behave (cf https://wg21.link/p2361).

`FormatDiagnostic` is modified to escape
non printable characters and invalid UTF-8.

This ensures that unicode characters, spaces and new
lines are properly rendered in static messages.
This make clang more consistent with other implementation
and fixes this tweet
https://twitter.com/jfbastien/status/1298307325443231744 :)

Of note, `PaddingChecker` did print out new lines that were
later removed by the diagnostic printing code.
To be consistent with its tests, the new lines are removed
from the diagnostic.

Unicode tables updated to both use the Unicode definitions
and the Unicode 14.0 data.

U+00AD SOFT HYPHEN is still considered a print character
to match existing practices in terminals, in addition of
being considered a formatting character as per Unicode.

- When using class templates without arguments, clang now tells developers
that template arguments are missing in certain contexts.
This fixes `Issue 55962 <https://github.com/llvm/llvm-project/issues/55962>`_.
- Printable Unicode characters within `static_assert` messages are no longer
escaped.
