Make target for running LVS and DRC standalone

[marwaneltoukhy]

There should be a make target that users can use to run LVS and DRC on standalone designs, without having to integrate it with the user_project_wrapper and running precheck.

Precheck already has python scripts to run DRC and LVS on standalone designs, but it just needs to be exposed using a make target.

In 12/18/2024 Shuttle meeting:

LVS is complete (make lvs )
Marwan can add the DRC and OEB target in 10 minutes for public use.
He will create the other individual checks (undocumented) for our use in debug with customers.
