gitlab CI: split the qemu test runs up into multiple jobs

The tests are split by topic but have varying runtime. Specifically, the
longest test (touchpad) takes ~170s whereas many of the others can take less
than a second. Splitting them all up into separate VMs costs too much in
startup time so here's the middle ground of some custom grouping to make the
tests roughly run the same time.

This list will need to be manually maintained but given that groups are rarely
added anyway this shouldn't be too much of a maintenance burden. And bonus:
since the kvm tests often fail due to timing issues, re-running one is
significantly faster now.

This shaves about 8min of the CI run
