Eliminate acquiring WM lock when bind/unbind service

There were lock contention between AM and WM when an activity
binds/unbinds service from:
- Associate the connection to the activity
- Add connection
- Remove connection
when WM is running layout/animation or updating config.

This change applies:
- Use a separated lock to manage the connection.
- Cache the visible state for BIND_ADJUST_WITH_ACTIVITY.
to eliminate the lock contention.
