Copy PipTouchStateTest to pip2 unit tests

PipTouchStateTest is identical between pip1 and pip2, copy over the unit
test class as well.

For the following classes copied from pip1 to pip2, extra changes have
to be made for the corresponding unit tests

- PipController
- PipResizeGestureHandler
- PipTouchHandler

Flag: com.android.wm.shell.enable_pip2
