Charm HLT2 lines related to detection asymmetries

This MR adds HLT2 lines related to Cabibbo-favoured modes to measure 2-track asymmetries. They are close to the equivalent of what we had in Run 1/2. The main principle is to keep the selection separate from the standard lines, as we typically require lower pT cuts, but so far used a cut on the IPCHI2 in the trigger to lower the rate.

All of the cuts are basically untuned, but all of the particle combinations are kept separate to allow for tuning later.

Edit mstahl: Rate increase with other charm lines 1.6 kHz. Inclusive rates:
