[Common, PWGHF, Event Filtering] Implement specific method to tag prompt/nonprompt charm hadrons

[fgrosa]

This PR implements a specific method to tag prompt/non-prompt charm hadrons, as discussed in Nonprompt_tagging_fgrosa_2022Jul04.pdf.

I just have a doubt regarding the output values of the checkCharmHadronOrigin function: they correspond to the hf_cand::OriginType enum, but are independently defined since the HF code should not be included in the common one. A possible solution to have it uniquely defined would be to move the hf_cand::OriginType enum in the Common code, or alternatively to move the method checkCharmHadronOrigin in the HF code (however it could also be useful for DQ, since it can be used to tag charmonia as well). @vkucera do you have suggestions?

Hi @fgrosa , thanks for this implementation. I agree that the output of checkCharmHadronOrigin and OriginType should be synced independently of the HF code. I would be fine with moving OriginType into RecoDecay. It should not change anything about the includes because RecoDecay.h is already included in HFSecondaryVertex.h. What do you think?

Hi @vkucera, thanks for your feedback! Indeed I also think it's a good solution, so I implemented it in the last commit.

Thanks @fgrosa

Since it is fine for @vkucera, @iarsene could you please approve it? Thanks a lot!
