Add option to disable all non-root presolve

[fwesselm]

• This PR adds a new boolean MIP option mip_root_presolve_only which, if set to true, disables all non-root presolve (i.e. during heuristics, etc.). The default value is false.
• For example, this option may be helpful in debugging presolve issues.
• A current limitation is that presolve may still be applied after a MIP restart.
• A test was added.
