Subject: Add github's CodeQL scanner to CI.

lgtm.com was acquired by github. It is deprecated and on its way out,
because they've integrated the functionality itself into github. Take a
look at what its official replacement can do.

This does run as yet another Actions slot, which is already fairly
excessive, but the average runtime seems about 5 minutes so that's not
too bad...
