Addressed and handled guest mode, screen off vs keyguard race condition, and screen off before lock condition

- Added a 2 fallback checks to mitigate keyguard and screen off race condition and lock after screen timeout setting
- Added a check to only reenable USB if user is not a guest
- Added an extra check to make sure that the USB port state is disabled, since in some HIDL implementation disabledForce can represent for framework's intent. Also added a request boolean to make sure DISABLED_FORCE is actuated by (if not partly by) APM so that it does not take action if itself did not expect USB to be disabled (ie. Enterprise policy)
- Added a lock to the critical section to avoid race condition between the multiple calls to setUsbDataSignalIfPossible()
- Removed data role check for determining if any existing connection should block disabling USB
