[PWGHF] Add configurations for D2H XiC0, XiC+ and OmegaC MCs (gen only, no gap trigger)

[fcatalan92]

@fgrosa @fcolamar @mfaggin @creetz16 @pstahlhu @stefanopolitano, this PR adds the ini files for the production of generated MC pools for XiC0 + XiC+ and OmegaC0 (separately for charm and beauty)

P.s. I launched the tests for these configurations locally (but they are slow as we know)

Thanks @fcatalan92! Same issue with the tests here as in my #1833 (let's see if it is solved now after having retriggered the tests)
