[Common,PWGHF] Add reduced workflow for B+, B0s -> J/Psi X analyses

[fchinu]

This PR adds the reduced workflows for the B+ and B0s meson analyses for their decays into a J/Psi and a K+ and phi, respectively. The considered decay of the J/Psi is that into a muon pair at midrapidity, and this workflow is meant to be used for the newly-developed HF software triggers for 2025 pp data taking. A runJPsiToee is also available in order to validate the workflow using the already existing MC simulations of B -> J/Psi X -> ee X.
In a following PR the workflow of B0 -> J/psi K*(892)0 -> (µµ) (Kpi) will be added, following what was done for the B0s -> J/Psi phi -> (µµ)(KK) workflow.

I would not feel super comfortable in fixing the O2 linter error
error: Workflow name task-omegac0-to-omega-pi does not match its file name taskOmegac0ToOmegapi.cxx, but of course if would you like me to do something in this PR I can do it, if the Omegac analysers are okay with that!

That's OK. That error is unrelated to your code and PR. Thanks for fixing the rest.

Hi @fchinu thanks a lot for the developments! I have checked everything except for the tasks, since there are a few "major" things to change first I think.
For the tasks instead, we could even consider to have a combined one (but maybe we see after all the comments are addressed)

[vkucera]

It seems that the MC matching is still using local enums and bitmaps instead of the enums from the main header.

[fgrosa]

Hi @vkucera @fchinu sorry to comment only now, but the flags in the main header are not good as they are; all the flags for the channels with JPsi should be in the same enum (because one can be background for the other), and they should not be split between resonant and non resonant (unless for the Bs -> JPsi Phi you add a correspondent non resonant channel Bs -> JPsi KK, but I am not sure if it is necessary, since only the resonant should be relevant).

Also please add values in the enum only at the end, because if you add them in the middle, they shift all the other flags (fine now that they have been just introduced, but this has to be avoided because it can create a complete mess as soon as people start producing derived data with these flags). It is more important than keeping the mother particles grouped (even if not "nice" it is not error prone as adding values in the middle). Thanks!

Please also make sure to apply IWYU and sort the includes with the latest clang-format configuration.
Also please fix the linter errors related to your code.

@vkucera MegaLinter is failing but the headers are ordered as described in the documentation (i.e. C++ headers at the end). The latest .clang-format was used to get this ordering. Can we merge as it is?

[vkucera]

Thanks @fchinu ! Looks good to me.
