[QS] Add PageIndicator to footer

Allow the footer to provide a new PageIndicator to the QSPanel.
Wrapped the cellular text/info in a LinearLayout such that it
fills the space available and updated params for the action
container depending on what orientation we're in.

Since we're swapping the page indicator, it's important not to
lose num pages/location, so additionally storing & resetting
those values when swapping.
