selftests: tc-testing: test action batch deletion failure cleanup

Add tests for cleanup after a batched RTM_DELACTION request fails at
a gact action bound to a filter. Check that subsequent actions retain
their original reference counts and that earlier successful deletions
are preserved.

Cover failures at the first and middle entries. Verify that a remaining
unbound action can be removed with one subsequent delete.

selftests: tc-testing: test action batch failure cleanup

Add tests for cleanup after a batched RTM_NEWACTION request fails.
Replace an existing gact action bound to a filter, then fail a later
entry by requesting goto chain without a classifier context.

Check that the bound action's reference count returns to its original
value. Also cover a successfully initialized new action between the
bound action and the failing entry, verifying that its reserved index
can be reused. Repeat the bound action in another batch to check that
each temporary reference to the same action is released.
