pw_env_setup: use latest versions of LUCI tools

Since LUCI tools aren't used in the Pigweed build, always grab the
latest versions of them. These tools are frequently updated but small
so bootstrap shouldn't take noticeably longer than before.

I went into pw_doctor to check that it didn't verify versions of the
LUCI tools and confirmed it does not. Added a comment clarifying this.

Also no longer get yapf from cipd. We never used that, we also got it
from pypi and we use that version. Also removing vpython, lucicfg, and
preview_email which were not used, and adding bb (the buildbucket
client).
