Add isctest.mark.with_developer pytest mark

Tests that exercise instrumentation, log output, or other behaviour
that only exists in developer builds (the gcc:almalinux9:amd64 CI job
sets -Ddeveloper=disabled to guard against such accidental coupling)
can now decorate themselves with isctest.mark.with_developer to skip on
non-developer builds.
