Remove CUP from google_apis

Remove CUP from google_apis

It was committed 13 months ago, and has seen no activity sense.
I failed, as a reviewer, for not ensuring that an appropriate
BUG was filed to track exactly why this code was being included,
how it would be used, and who would own it.

Even if this code "might" be used in the future, 13 months of
inactivity suggest it's time to remove this code, especially
when it's only half-implemented.

BUG=none

rogerta: Please review google_apis
ryanmyers: FYI, as the only person apparently who worked on this code.

We can reland it when you need it.

LGTM.

This code was intended to be used by Chrome's Component Updater, to allow an
alternative to HTTPS.  However, that work has been deprioritized for multiple
quarters, in favor of higher-priority work items; and at this point, we'd prefer
to use CUP-ECDSA (based on SignatureVerifier) instead of CUP-RSA anyways.
