Trampoline SMS disambig dialog to Telephony

SmsManager used to display a "select default SMS
subscription" dialog every time SmsManager was used
and no default SMS subscription was set. This change
fixes the following issues:
1_ getSubscriptionId no longer pops up a disambig
dialog.
2) The disambig dialog no longer sets the
default, rather it waits for the response from the
user and performs the operation when it receives
a response.
2a) Dialogs can no longer be created from background
services, so we now have a restriction that if
the disambig dialog is shown via a background service,
we will use phone 0 as default (backwards compat for
apps targeting <Q) or fail (on apps targeting Q+).
3) If there is only one active subscription, use that
to perform the operation on MSIM devices instead of
asking and only displaying the one active subscription.
4) Certain non "user-facing" APIs that are used by
carrier apps no longer will pop up a UI.
