Updates to rotation options

Taken from upstream:
Forced orientation are now locked
Free-ish modes is now Portrait/Landscape instead of lock
Rotation button in bottom sheet toolbar (default off)
Popup menu helper method

Also because it's getting crowded, updated layouts of the buttons in the sheet to compress themselves a bit if people go crazy (though display options will always be full width)
