Long running OR commands should report their runtime

Description

Every “long running” command should report how long it took to run it. The goal would be to be able to easily compare log files from different runs. E.g. vimdiff dir[12]/log or grep runtime dir2/log > dir2/runtime diff dir[12]/runtime

Suggested Solution

Currently there seems to be a way to get ORFS to report runtime and memory usage. But this relies on running the openroad executable for each and every step. And it's not "built into" openroad, it relies on external scripting. It should be possible to have one OR tcl script to run "the whole flow" and still get this information in the log.
