We aren't setting it for the STA done in the routing step. Part of the problem is we sometimes call STA with `RUN_STANDALONE=1`  and sometimes we dont. <@U020J2W6Q84> any idea why?

I presume that's just to get it logged to a separate file?

<https://github.com/The-OpenROAD-Project/OpenLane/pull/946> makes sure we always call `set_propagated_clock[all_clocks]` after CTS. I put it immediately after `read_sdc`to make it obvious. run_sta (ie `STANDALONE=1`) is still broken however.
