Introduces the possibility to have variable precision, e.g. Float64.
Updates the arguments of the VTKOutputModule constructor and adds the
version check for dune. Default stays Float32.

This reverts commit 17e2a139.

* use template specialization to deprecate old interface
* phaseIdx cannot be used anymore due to the variadic template

[io] Revert change from 26600833 because staggerd returns real num dofs from grid geometry

This commit will enable the geomechanics framework to not have to
state the number of phases in geomechanical model traits. Also, when
velocity output for the geomechanical models is implemented, we will
have to distinguish in the vtk output module anyway, as then we would
have to call numSolidPhases(). Outsourcing it directly to the velocity
output seems like an elegant solution.

Geomechanical models will not be able to reuse the vtk output module
otherwise.
