Merge branch 'github-ci-asan' of https://github.com/thesiv/wxWidgets

Switch to GitHub Actions for the ASAN CI build: running it on Travis CI
often fails (see https://github.com/google/sanitizers/issues/1353),
making it more trouble than it's worth, so try running it on GitHub
instead.

If it works fine there, we can move more Travis CI builds to that
platform later.
