Mark de Wever 4761a74fd8 [libc++][CI] Updates and improves the Docker image. 
Since we branched LLVM install Clang 16 and remove Clang 12.

Currently our Docker installs 4 versions of Clang so our CI can use the
same image for both the main and the release branch. This wasn't done for
the other Clang tools so they always use the same version for testing
the main and the release branch. Instead install 2 versions for the
tools.

However it seems the default for Clang and its tools were the latest
released version instead of the ToT. To lessen the risk of breaking the
release CI, version 14 is installed hard-coded as a temporary solution.

Updating the main branch to use the Clang 16 compiler will be done in a
separate patch.

Mark de Wever f7c0df002a [libc++][format] Improve format buffer. 
Allow bulk output operations on the buffer instead of adding one
code unit at a time. This has a huge performance benefit at the cost of
larger binary. This doesn't implement @vitaut's earlier suggestion to
avoid buffering for std::string when writing a strings. That can be done
in a follow-up patch.

There are some minor complications for the non-buffered format_to_n.
When writing one character at a time it's easy to detect when reaching
the limit n. This is solved by adding a small overhead for format_to_n.
When the next write would overflow it stores the data in the internal
buffer and copies that up-to n code units. The overhead isn't measured,
but it's expected to only be an issue for small values of n; for larger
values the general improvements will outweight the new overhead.

For very small strings the new method is slower, from 4 characters
there's already a small gain.

The int benchmark has benefits for the simple formatting, but shines for

David Blaikie c63f2581f4 Enable -Wctad-maybe-unsupported in LLVM build 
Warns on potentially unintended use of C++17 Class Template Argument
Deduction. Use of this feature with types that aren't intended to
support it may may future refactorings of those types more difficult -
so this warning fires whenever the feature is used with a type that may
not have intended to be used with CTAD (the warning uses the existence
of at least one explicit deduction guide to indicate that a type
intentionally supports CTAD - absent that, it's assumed to not be
intended to support CTAD & produces a warning).

This is disabled in libcxx because lots of the standard library is
assumed to provide ctad-usable APIs and the false positive suppression
in the diagnostic is based on system header classification which doesn't
apply in the libcxx build itself.
