Add three new lines to select charged kaon decays in HLT1 for Run 3

This MR includes a 3-body SV maker (as compared to the current 2+1 combinations) and a set of lines to select three-body charged kaon decays in HLT1. For now only

$\pi e e$

,

$\pi\mu\mu$

and

$3\pi$

are implemented. The lines' cuts have been aligned with their analogous HLT2 lines Hlt2RD_KpToPiMuMu, Hlt2RD_KpToPiPiPi and Hlt2RD_KpToPiEE. In addition, the

$K \rightarrow 3\pi$

has been pre-scaled to 0.01.

All lines have been tested locally on expected 2024 minimum bias bandwidth division samples with the sequence hlt1_pp_forward_then_matching_1200KHz yielding the following rates:

Hlt1Kplus2PiEE:                                     9/200000, (    1.35 +/-     0.45) kHz
Hlt1Kplus2PiMuMu:                                   6/200000, (    0.90 +/-     0.37) kHz
Hlt1Kplus2PiPiPi:                                   2/200000, (    0.30 +/-     0.21) kHz
Inclusive:                                       9909/200000, ( 1486.35 +/-    14.56) kHz

Without the new lines for comparison:

Inclusive:                                       9895/200000, ( 1484.25 +/-    14.55) kHz

So the lines add about 2 kHz.

The throughput check yields

Device                        Throughput (kHz)    Reference Throughput (kHz)  Speedup    % change    Status

Device-averaged speedup: 0.97x
               % change: -2.87%
                 status: DECREASED

with a few % slowdown on the CPU and 2080 NVIDIA GeForce RTX 2080 Ti card and ~ 1% slowdown in the rest. This decrease is mainly due to the 3-body SVs combiner which this MR adds.

Todo:

• Test using 2024 expected minbias and signal MC
• Add LFV decay combinations (this could be postponed to a second stage)
• Adapt to the new monitoring machinery from @ahennequ once it is merged (see !1483 (merged))

Uses the new 2+1 body combiner machinery from @mstahl and @thboettc
