Update placement of the hotseat according to the bubble bar location.

Update the hotseat and Qsb placement according to the 3 nav buttons bar.

Test: Manual.
Set navigation mode to 3 buttons.
On launcher home screen move the bubble bar from one side to another.
Observe that the Hotseat and Qsb moving together with the navigation
bar.
Once moved the bubble bar, expand the bubble bar and collapse it.
Observe how the Hotseat is stashing and un-stashing.
After bubble bar changes position hit the recent apps button, observe
the transition.
On launcher home screen start application with the hotseat icon and exit
opened application. Observe that flying icon comes back to the correct
position in the hotseat.
Video with the above scenarios:
