MUON: add plots with global kinematics (#2378)

* [MUON] added plots from global tracks kinematics

Some additional kinematics plots are introduced for eta, phi and pT
distributions that are filled using the parameters of the global
MFT+MCH(+MID) forward tracks.
The additional plots are only instantiated when MFT is included in the
required detectors.
The already existing plots are now always filled using the MCH track parameters.

Five other plots have been disabled by default, to compensate the newly
instroduced plots (which are also five by default).

* [MUON] reshuffled histogram instantiation

Cosmetic-only modification to better logically group the
histogram instantiations.

* [MUON] clang formatting
