Added new solver-specific tags for SMT regression tests

[SaswatPadhi]

As per the proposal described in #5982 and offline discussions with @tautschnig, this PR introduces new tags that can be used to label tests that are known to be broken with specific solvers. It also updates the Makefile targets to use these solver-specific tags.

This PR would unblock #5973. The regression test there was tagged broken-smt-backend and has been fixed to work with Z3 and CVC4 (and other solvers that support quantifiers), but currently there is no viable fix for CPROVER SMT2. Once this PR is merged, I would label that regression test as broken-cprover-smt-backend instead.

• Each commit message has a non-empty body, explaining why the change was made.
• NA Methods or procedures I have added are documented, following the guidelines provided in CODING_STANDARD.md.
• NA The feature or user visible behaviour I have added or modified has been documented in the User Guide in doc/cprover-manual/
• NA Regression or unit tests are included, or existing tests cover the modified code (in this case I have detailed which ones those are in the commit message).
• NA My commit message includes data points confirming performance improvements (if claimed).
• My PR is restricted to a single feature or bugfix.
• NA White-space or formatting changes outside the feature-related changed lines are in commits of their own.

Note that I have added additional targets to the Makefile but those are not built as part of the default target (that's run on the CI). I didn't know of a way to do that with cmake -- using add_test_pl_profile directly adds them to the build queue.

This is more distinctions than I would make but ... if you are happy to work with these then, cool.

Thanks for taking a look @martin-cs.

I removed the cvc4 tags for now since we don't run cvc4 on CI. I will keep #5982 open for further discussion and we can add more tags later if we need to.
