TrigAnalysisTest: add MC grid test comparing CA vs legacy counts

Hello,

Similarly to !67637 (merged) which introduced a test comparing CA vs legacy trigger counts in data, this MR introduces a test comparing CA vs legacy counts for MC. The input is a mix of ttbar, stau, and bphys samples, in order to maximise the coverage in terms of trigger menu. The test uses 8 threads, 2500 events, and runs in ~2h30.

Tagging @khoo , @sshaw , @mark , @cpollard for info.

Cheers, Bertrand
