Updates to PyROS Solver Timing System

[shermanjasonaf]

Summary/Motivation:

Update PyROS solver timing system, subordinate solver call routines, and subordinate solver time limit adjustment routines.

Changes proposed in this PR:

• Standardize calls to subordinate solvers across all PyROS subproblem types
• When adjusting PyROS subordinate solver time limits, account for user-specified options
• Add support for SCIP subordinate solver time limit adjustment
• Start main PyROS solver timer just before argument validation begins, rather than just after argument validation is complete

@shermanjasonaf I cancelled the latest build. I'll relaunch the tests after #3222 is merged in.

This looks good to merge once we hear back from @shermanjasonaf on what (if anything) should be done WRT symbolic_solver_labels.
