Enable concrete playback for failure of UB checks

[zhassan-aws]

Description of changes:

Currently, Kani only generates concrete playback tests for checks with the "assertion" property class. This PR enables generating concrete playback tests for other classes of properties as well (e.g. UB checks). Executing those tests normally will likely not result in a failure, but running them with MIRI should show the failure.

Resolved issues:

Towards #2163

Related RFC:

Optional #ISSUE-NUMBER.

Call-outs:

#2163 suggests that concrete playback tests that result in UB should be classified separately. This PR doesn't do that yet, hence I didn't mark it as a resolver for #2163.

Testing:

• How is this change tested? Added two new tests

• Is this a refactor change? No
