PointerIcon: Add leniency to hotspot validation for scaled icons

When icons are loaded for the current display density, the icon bitmap
is always scaled to an integer pixel size, but the hotspot can be scaled
more precisely using floats. To account for the difference in precision,
add leniency to the hotspot validation checks when the icons are scaled.

Test: adb shell wm density 142
