clusters/halo: Add velocity_turb_base() method
This method calculates the velocity dispersion of the base turbulence,
i.e., the turbulence existing in a relaxed system without the merger
injection.
Add new configuration option 'extragalactic/halos/x_turb' to
parameterize the energy fraction of the base turbulence w.r.t. the ICM
thernal energy.
