Enable options for controlling booster execution

This PR takes advantage of a few new features introduced in pyk, and makes a few updates to CLI and testing options:

• Option --fast-check-subsumption allows a faster way to check that a node will definitely not be subsumed into the target.
• Option --always-check-subsumption allows checking even non-terminal node for subsumption.
• Options --[no-]post-exec-simplify allows telling the booster to not call the old backend to simplify states that it produces before handing them back to pyk (see (Dev.) Options to control fall-back reasons and post-exec simplification hs-backend-booster#436).
• Option --fallback-on allows the user to specify the fallback reasons the booster will consider (see (Dev.) Options to control fall-back reasons and post-exec simplification hs-backend-booster#436).
• Option --interim-simplification allows the user to specify how frequently to invoke the full simplifier on the execution state.
• By default, all breaks are turned off for testing purposes (which mimics CLI behavior better). Before, we had break_on_calls set to True for testing/CI behavior, but False for CLI behavior, which made it hard to track down a bug.
• An option --spec-name is added to make test-prove-pyk ... pytest testsuite, which allows filtering for a specific specification to run in the testing harness environment (much faster to narrow down to specific test that way).

It looks like you and Andrei have had some back and forth on this one. Is there an ETA to merge this one?

Approved with a typo fix. 👍
