github: Add an optional set of smoke tests for github actions

This adds an optional github actions workflow, with a number of
smoke test verifications of mingw-w64:
- With an existing release of llvm-mingw, rebuild all the runtimes
 - This done for the CRT configurations ucrtbase, ucrt and msvcrt
- Run the llvm-mingw smoke tests on Windows (testing compilation
  for all 4 architectures, testing running on x86)
- Run the libcxx testsuite on Windows (i686 and x86_64)
- Test cross-building ffmpeg for all 4 architectures
- Test building and running ffmpeg with its testsuite on Windows
  (i686 and x86_64)
- Test building a GCC cross compiler from scratch
- Test cross-building a Windows hosted GCC using the GCC above
- Run a small set of basic tests with the GCC toolchain

This allows doing some amount of automatic testing of mingw-w64,
covering most common build configurations, avoiding regressing
any of these cases.

While mingw-w64 isn't primarily hosted on github, this wouldn't
be a mandatory/integrated testsuite per se. But many mingw-w64
developers do use github and can benefit from this test setup,
and by having it in-repo, it's easier to coordinate updates to
the test configuration when that is needed. It also makes it
easier for others to contribute more testing configurations.
