Cleanup deprecated or removed telephony methods.

Mark previously deprecated TelephonyManager APIs as @remove; some of these
have valid public APIs; for now just calling the public APIs to give more
time for API consumers to transition over to the new methods.

Remove ITelephony AIDL calls for removed methods.

Removed ITelephony light greylist for removed methods; see bug for details.
There are public alternatives for most of the remove AIDL methods; a couple
of the subscription specific ones are not available directly but the
non-subscription specific versions should suffice.
