Allow exec groups to inherit from the rule or other exec groups.

Work towards #12006.

Add a "test" exec group for TestRunnerActions. This will allow users to set {"test.key", "value"} inside their exec properties and {"key", "value"} will propagate as to just TestRunnerActions.

This addresses user request #10799

This is a rollforward of c1ae939, which
was reverted in c266ac9.

Closes #13119.
