This adds the public API to configure an eraser button on a tablet tool
to emulate a normal button. In DEFAULT mode the eraser button will
simply do whatever it does by default (i.e. toggle to eraser).
In BUTTON mode the eraser button will be converted to a regular tool
button event, with libinput handling the underlying proximity event
madness.

This adds the configuration option to define a rectangle that serves as
an input area on external tablets such as an Intuos.
The intention behind this is to make this input area behave as if it was
the only physical input area on this tablet with libinput emulating
proximity events as required for where the tools moves in and out
of this area.
This could also be achieved with the existing calibration setting but
area configuration is not calibration and we don't want to expose other
side-effects of the matrix (e.g. scaling and rotation) for these
devices.
Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1013>
Add a configuration option to reduce the available hardware range to a
fraction thereof. This is done by copying the absinfo struct for the
pressure value and adjusting that copy's minimum/maximum value for
scaling into the target normalized range.
The 1%/5% tip thresholds are kept but pressure offset detection is
disabled if there is a custom pressure range.
Unlike the pressure curve which is implemented in the compositor, the
pressure min/max range needs to be in libinput, primarily because the
tip threshold needs to adjust to any new minimum, allowing for
light touches with a pen without triggering tip down even at a higher
hardware pressure.

detect_pressure_offset() currently rejects offsets that are greater than
20%. My graphics tablet (Wacom Bamboo Fun) is about 30%. The pen tip is
2 mm. Wacom recommends replacing at 1 mm, which means this isn't worn
out yet and we should instead increase the limit to make these devices
usable.
Without this change a "pen down" event happens simultaneously with the
pen being detected -- about 1 cm above the surface -- and producing
libinput pressure of about 0.30. This means you start drawing "in the
air", without knowing up front where the cursor is going to be.

This is a large commit because it's difficult to split this up and we don't
care about bisecting here anyway.
doxygen is going to produce the API documentation only
sphinx is going to produce the prose user (and a bit of developer) documentation.
The source split is doc/api and doc/user.
Steps performed:
- run the doxygen-to-sphinx.sh script to convert all .dox sources to .rst
- manually fixed the .rst to render correctly
- add a few extra .rst documents to generate the right hierarchy
- hook up sphinx-build in meson
- add a new @mainpage for doxygen more aimed at developers
For the build directory:
- sphinx produces /Documentation
- doxygen now produces /api/
These need to be manually combined in the wayland-web repo, meson doesn't
support subdirectories as output paths within the build dir and the
documentation doesn't need to be installed anywhere.
