Motivate of the pull request

Given PR implements RG-233 task and introduces timing report table for Placement/Routing tasks.

Describe the technical details

Placement timing report has already been created as a file, however we didn't retrieve actual values but placed entire lines there. After this development actual timing values will be retrieved and put into a structured report (table). The same is implemented for Routing. Text is slightly different from Placement, but structure is the same and I could reuse the same parsing logic for both, with a tiny tweak.

What does this pull request change?

• New reports added to Placement/Routing (in context menu and Reports view):
• Structured report is created:
• next to placement, the file is also created for Routing (post_rout_timing.rpt):
