Remove google analytics entirely.

This CL removes the last remaining traces of GA from files app.

It does not replace the remaining metrics that were being recorded
with UMAs, we're removing them as well as either:
a) There's coverage via an existing UMA, or
b) We don't care to record that metric anymore.
