Now that all jobs have moved over to the new style of Lit configuration,
we can remove all traces of the legacy testing configuration system.
This includes:
- Cache settings that are not honored or useful anymore
- Several CMake options that were only useful in the context of the
legacy Lit configuration system
- A bunch of Python support code that is not used anymore
- The legacy lit.cfg.in files themselves

Since dfa88927ae, the static
libc++experimental should work in mingw dll builds. (It probably worked
all along in static mingw builds.)

Since a8d15a9266 / D110975, this is
the default, even if winpthread headers are available, so we don't
need to cargo cult setting this option in all builds.

This is similar to the existing setting LIBCXX_ABI_DEFINES, with
the difference that this also allows setting other defines than
ones that start with "_LIBCPP_ABI_", and allows setting defines
to a specific value.
This allows avoiding using LIBCXX_TEST_COMPILER_FLAGS in two
CI configurations.

Mention support for MinGW in the docs. Rename the existing windows
CI jobs to Clang-cl, as both Clang-cl and MinGW are equally much
"Windows", just different toolchain environments.
Add an XFAIL for a recently added test that fails in the MinGW DLL
configuration (with an explanation of what's causing the failure).
