Remove all baremetal bots, baremetal tests will be part of *_rel

See https://chromium-review.googlesource.com/c/chromium/tools/build/+/1058799
After the baremetal machines are moved to swarming, that CL will add the tasks that were previously in *_baremetal bots to *_rel bots. *_rel bots will run all the same tasks as before on a pool of generic machines, but also run a few tests on dedicated baremetal machines (pool:WebRTC-baremetal-try).

No-Try: True
