Try splitting up integration tests (#25312)

Follow up to #25271 and #21774

Integration test failures will happen much faster of they occur, but now
the bottleneck is the `fleetctl` test suite.

It's trivial to continue splitting tests up now. We should look into
creating an action that checks that mock generation is up-to-date, run
it before all the tests, and then remove the mock generation step from
each test step. That would save about a minute and a half of runtime
from each test and help offset the cost of splitting the tests up.
