gatt: Allow GATT server to dicate CCC permissions Allow a GATT server to impose write permissions/restrictions on a CCC by setting additional `X-notify` and `X-indicate` flags on its associated characteristic. This allows a developer to require encryption/authentication in order for a GATT client to subscribe to server-initiated updates. ``` [bluetooth]# register-characteristic\ 4b75f0f8-1f23-46b1-900c-5bbabcd5ca93 encrypt-read,encrypt-notify [NEW] Characteristic (Handle 0x0000) /org/bluez/app/service0/chrc17 4b75f0f8-1f23-46b1-900c-5bbabcd5ca93 Vendor specific [/org/bluez/app/service0/chrc17] Enter value: 42 ```
