Enable win_linker_timing on Windows CFI and ThinLTO bots

This passes the /time option to LLD, which prints out some statistics
about how long various linking phases took. I plan to add more timers
around the major LTO phases so we have more visibility into how ThinLTO
performs on buildbots.

Also remove two CFI bots that moved from chromium.fyi to chromium.clang.
