(distr) inputanalog_query to wmsupport.lua for touchscreen range

If possible, will use information returned by inputanalog_query to calibrate touch input range.
Otherwise will fallback to display dimensions as it was done before.
Autorange algorithm is kept just in case the touchscreen doesn't provide it's range and does not match the display dimensions.
