libinput: Add support for configuring pressure range of tablet tools

Joshua Goins requested to merge work/redstrate/tool-pressure-range into master

This was added in libinput 1.26 (hence the dep bump) and allows limiting the logical range of tablet tools between 0.0 and 1.0.

To allow this, two main configuration options were added to Device, pressureRangeMin and pressureRangeMax. Applications can then query if this is supported via supportsPressureRange or reset it to defaults with defaultPressureRangeMin/Max.

The API is a little odd to work with, so we are unaware of if the tablet tool supports pressure ranges until we receive the first event.
