Both time steps are created from the timestepper,
so this construction is moved inside the ProcessData.

This resolves the warning about the time step not being
passed by reference, are removes the unnecessary std::move
in the caller for the time step.

Small reformatting if string literals.

The 'name' in process construction is also used after
the process construction and so it can not be moved
anyway. Taking it by const-ref avoids an extra copy
here (and silences a cppcheck warning).

These are dangling-reference, array-bounds, and stringop-overread.
This is the same as the exception for gcc-13.1.1.

The 'next' value is not used afterwards.

Fixes "The initialized value is overwritten before it is read." warning.

Returning false when conversion would fail instead of
OGS_FATAL. The OGS_FATAL happens on the caller side.

This allows to supply different forces/gradients blocks
then the forces/gradients of the solid model. E.g. material
model is driven by deformation gradient and computes new
stress but the tangent operator gives derivative of stress
w.r.t. strain and not to deformation gradient.

The default behaviour is using forces/gradients of the
solid material model.
