Sam Rawlins 7253f6198d infra: combine all three "analyze flutter" scripts.
The previous three scripts had some redundancies:

* Both the flutter/flutter analyzing script and the flutter/packages
  analyzing script checked out flutter/flutter. Combining them saves
  several minutes.
* The script that analyzed flutter/engine was pointing to the old
  engine repo, which was archived months ago. In pointing the script
  to the new sources at flutter/flutter, this would introduce another
  instance of cloning flutter/flutter. Combining this with the other
  scripts saves several minutes.

The only other little changes to the code are the introduction of
more echo commands, more `pushd`/`popd` vs `cd`, and isolating the
three tasks into functions for readability.
