extmod/modbluetooth: Merge gatts_notify/indicate implementation.

Browse Source 
Makes gatts_notify and gatts_indicate work in the same way: by default they
send the DB value, but you can manually override the payload.

In other words, makes gatts_indicate work the same as gatts_notify.

Note: This removes support for queuing notifications and indications on
btstack when the ACL buffer is full. This functionality will be
reimplemented in a future commit.
