Add the ability to run tests with variable collection methods

[Molter73]

Description

More importantly, this allows to set the collection method to include the new core_bpf driver. This collection method and now be added for PRs using the 'run-corebpf-tests' label.

Fixes #1067

Checklist

• Investigated and inspected CI test results

Testing Performed

• Ensure running CI with run-corebpf-tests runs the tests with the core_bpf collection method.
• Ensure running CI without run-corebpf-tests skips the tests with the core_bpf collection method.

Just realized benchmarking is not being run for the CO-RE bpf probe (or at least it is not showing up in the commit), I'll try to add that as part of this PR as well.

Benchmarks seem to be running with the CO-RE bpf probe now, but they are not being shown in the report because it is not present in the baseline file (and it won't be until we run benchmarks on the master branch).

LGTM! I think there's probably some more we can do to consolidate the uses of collection method throughout the playbooks (so there's less duplication) but that can be done in a follow up I think.
