gui: less click+wait, populate timing paths as part of loading timing

oharboe · oharboe · commit 217926693f8f · 2024-10-12T07:55:13.000+02:00
This makes the GUI more responsive for large designs
when interacting with timing.

report_checks returns instantaneously.

Use GUI_TIMING=0 when timing is not needed.
