Speed up estimate_parasitics during GRT stage #5240

Closed eder-matheus closed 1 week ago

Following issue https://github.com/The-OpenROAD-Project/OpenROAD/issues/4833, the estimate_parasitics step in the design has a very large runtime. Improve it with parallelization or by optimizing the current algorithms performed in this command.

Actually, the large runtime at the end of the GRT stage in ORFS is due to report_checks, not estimate_parasitics.
