Make sure that touches are within the physical frame.
Right now we just check that touches are within the reported axis
bounds, but really we should be checking whether they're in the physical
frame before notifying the rest of the system about them.
Also, fix a bug in touch transformation code where translations were
being incorrectly applied. We should only apply top and left
translations when we're in portrait and landscape orientations, as in
seascape and upside down orientations they'll just exceed their stated
maximum naturally.
Bug: 112876936
Test: enable notchless simulation, try seascape apps, try swiping down
