Minor changes to presolve

[fwesselm]

• Add two utility methods HPresolve::checkUpdateRowDualImpliedBounds and HPresolve::checkUpdateColImpliedBounds to check whether bounds on row duals and columns can be updated.
• This allows for simplifying the presolve code a little.
• Testing showed that these change do not affect HiGHS behavior at all.
