CI: Remove the Sonar Cloud and PVS Studio workflow

Static analysis is great, but these workflows have not worked in a long
time, and no one was looking at the results. Our PVS Studio license and
our Sonar Cloud token have expired. Remove the workflows (at least for
now) so we don't waste CI runners and cache space. If someone is
motivated to revive these, they can revert this commit.
