This PR adds functionality to filter out tests during regressions for a
particular config.
e.g. if a full regression is kicked off using the `small` config, we
don't want to attempt to run any PMP and bitmanip tests as the RTL
parameter-set will not support it.
To do this, a new YAML field called `rtl_params` is added to relevant
test entries, to indicate what parameters (if any) are required to be
able to run the particular test, along with the required value of said
parameters.
`sim.py` will then parse this field (if it exists), and using
information from `ibex_configs.yaml` pertaining to the current config,
will remove tests from being run on-the-fly.
This also gives us the convenient side effect of not having to re-run
instruction generation if there is a parameter/config mismatch, we can
just rerun the RTL compilation and simulation stages safely.

Fix a deprecation, to be removed in Python 3.10.
See https://docs.python.org/3/library/collections.html:
