Using the haptic input feature freezes the app when a single tap is detected

Bug Report

When using the haptic input feature to detect the tapped view in a navigation app, the app freezes whenever a single tap is detected. This is because the library does not check on main thread if a view was tapped.

Reproduction Steps

1. Create a navigation app with some UIViews in the rootViewController (Make sure to send a SDLDidUpdateProjectionView notification to the library)
2. Connect to Core
3. Perform a single tap on a view on the SDL app

Expected Behavior

The touch manager should notify the subscriber right away that a view was tapped.

Observed Behavior

The app freezes for a few seconds before the notification is sent by the touch manager.

In the SDLFocusableItemLocator class, the viewForPoint: method should check if a tap is inside a view on the main thread.

OS & Version Information

• iOS Version: n/a
• SDL iOS Version: 6.2
• Testing Against: SYNC 3 and SDL_Core 5.1.0 + sdl_hmi
