Rename resampling property

The resampling property is currently '*.noresample', which is confusing
because it is false by default.

Test: enable 'DEBUG_RESAMPLING', in InputTransport,  then touch  the screen to see that
events are being resampled. This can be seen in the logcat.
Next, run 'adb shell setprop ro.input.resampling 0', adb shell stop &&
start and touch screen again. See that resampling is no longer active.
