Adds a new CMake option to disable the usage of incomplete headers.
These incomplete headers are not guaranteed to be ABI stable. This
option is intended to be used by vendors so they can avoid their users
from code that's not ready for production usage.
The option is enabled by default.

The unit tests test some implementation details. As @Quuxplusone pointed
out in D96664 this should only be tested when the tests use libc++. This
addresses the issue for code already in main.

Now that Lit supports regular expressions inside XFAIL & friends, it is
much easier to write Lit annotations based on the triple.

This has been broken out of D104170 since it should be merged whether or
not we go ahead with the module map changes.

This fixes a long standing issue where the triple is not always set
consistently in all configurations. This change also moves the
back-deployment Lit features to using the proper target triple
instead of using something ad-hoc.
This will be necessary for using from scratch Lit configuration files
in both normal testing and back-deployment testing.

Implements parts of:
- P0645 Text Formatting
Depends on D92214
Reland with changes:
The format header will only be compiled if the compiler used has support
for concepts. This should fix the issues with the initial version.

This reverts commit 35a57f39b5.
A build is broken during clang bootstrap with:
In file included from ../libcxx/src/format.cpp:9:
/tmp/ci-nGNyLRM9V3/include/c++/v1/format:153:16: error: no member named 'is_constant_evaluated' in namespace 'std::__1'
if (_VSTD::is_constant_evaluated() && __id >= __num_args_)
~~~~~~~^
1 error generated.
This is the first step at implementing <format>. It adds the <format> header
and implements the `format_error`. class.
