Implement onAllPermissionsGranted for rememberCallPermissionsState

Implement onAllPermissionsGranted for rememberCallPermissionsState.

This solution resolves #1026 by utilizing the onAllPermissionsGranted lambda to detect when all necessary permissions are granted, enabling us to proceed with joining the call.

CallContent(
    permissions = rememberCallPermissionsState(
        call = call,
        onAllPermissionsGranted = {
            call.join()
        }
    ),
  ..
)

At some point we'll have to consolidate all the various ways we have that tell us if the permissions are granted or not.
But this one fits nice with the rememberCallPermissionsState
