pw_env_setup: Allow using existing cipd client

Add --use-existing-cipd which will cause the cipd part of env setup to
use a 'cipd' executable already in PATH instead of downloading it anew.
This will be used in CI/CQ where pulling down the cipd client is an
infrequent but occasional failure, and there's a guarantee of an
existing 'cipd' executable anyway.

Tested by adding --use-existing-cipd to bootstrap.sh and it worked. Then
removed because most Pigweed developers won't have 'cipd' already
somewhere else in their PATH.
