Peter Hutterer e9f3fc080c tablet: revamp the tablet pressure range handling 
Commit 48cd4c7287 ("tablet: track pressure ranges per tablet") added
tracking of pressure ranges per tablet by storing ranges for multiple
(up to 4) tablets in the tool. This doesn't scale well, had the
disadvantage of the range only being updated on out-of-proximity, and is
the wrong approach anyway.

Turns out we can update the pressure range on proximity in since we
haven't processed the pressure values yet at that stage. This gives us
better behavior when switching between tablet devices (including unplug)
as the pen will only lag behind once (when setting the range) instead
of once per new tablet.

However, since the offset (which is a tool issue) applies on top of the
pressure range (which is a tablet property) this requires that we now
track the offset as percent of the range.

So on proximity in we apply the new tablet range, then apply the e.g. 5%
pressure offset within this range.

This means we no longer have to track multiple tablets since it'll just
apply on the current tablet when in proximity.
