Add target selection for cargo kani

[celinval]

Description of changes:

Add the following options to restrict cargo kani verification target:

• --bin <BIN_TARGET>
• --bins
• --lib.

I found this very helpful for example to skip integration tests when running cargo kani with --tests.

Resolved issues:

N/A

Related RFC:

Optional #ISSUE-NUMBER.

Call-outs:

1. Given the driver architecture, I explicitly added a check to ensure standalone Kani does not accept the new arguments.
2. These options were already added to cargo kani playback in Allow users to select the test targets #2491.

Testing:

• How is this change tested? New tests

• Is this a refactor change? No

In this change, we add those options to the overall verification workflow.

Can you clarify a bit the purpose of this change? Is it a cleanup PR or is it adding a new feature?

Sure. We are adding a new feature, and I believe the title "Add target selection" reflects that, but I can definitely expand the description.

Nice work! The tests are pretty neat.
