Before this Blender always needed the Wintab driver. This adds support for the
native pressure API in Windows 8+, making it possible to get pressure sensitivity
on e.g. Microsoft Surface hardware without any extra drivers.
By default Blender will automatically use Wintab if available, and if not use
Windows Ink instead. There is also a new user preference to explicitly specify
which API to use if automatic detection fails.
Fixes T57869: no pressure sensitivity with Surface pen or laptop.
Code by Christopher Peerman with some tweaks by Brecht Van Lommel.

This disables touch gesture recognition in Blender, avoiding any initial delay
when drawing with grease pencil, texture paint, etc.

This change brings back old original logic which was checking
whether worker threads do fit into an active CPU group. But
it does it a bit smarter now and is also checking affinity
within that group. This way Cycles will use all threads on a
Threadripper2 CPU if it's set to automatic number of threads,
but on another hand will not change affinity if user requested
16 threads and changed Blender affinity.
Tweaked scheduling so it survives this situation by scattering
"extra" threads uniformly over all the NUMA nodes.
There are still tweaks possible to make some specific hardware
configurations work better.

Does the following changes visible to users:
* Use panels and sub-panels for more structured & logical grouping
* Re-organized options more logically than before (see images in D4148)
* Use flow layout (single column by default).
* New layout uses horizontal margin if there's enough space.
* Change size of Preferences window to suit new layout.
* Move keymap related options from "Input" into own section.
* Own, left-bottom aligned region for Save Preferences button.
* Adjustments of names, tooltips & icons.
* Move buttons from header into the main region (except editor switch).
* Hide Preferences header when opened in temporary window.
* Use full area width for header.
* Don't use slider but regular number widget for UI scale.
* Gray out animation player path option if player isn't "Custom"
Internal changes:
* Rearrange RNA properties to match changed UI structure.
* Introduces new "EXECUTE" region type, see reasoning in D3982.
* Changes to panel layout and AZone code for dynamic panel region.
* Bumps subversion and does versioning for new regions.
RNA changes are documented in the release notes:

Design & implementation mostly done by @billreynish and myself.

Please always build tests when messing with build system/libs, am tired
of fixing that kind of issues...
Also, that fix is probably not working for standalone, no idea where's
the numaapi lib then, but committing since I need a building blender
here (with the tests, yes).

The issue was introduced by a Threadripper2 commit back in
ce927e15e0. This boils down to threads inheriting affinity
from the parent thread. It is a question how this slipped
through the review (we definitely run benchmark round).
Quick fix could have been to always set CPU group affinity
in Cycles, and it would work for Windows. On other platforms
we did not have CPU groups API finished.
Ended up making Cycles aware of NUMA topology, so now we
bound threads to a specific NUMA node. This required adding
an external dependency to Cycles, but made some code there
shorter.
Previously we would try to guess what the main tablet device is, but this is
error prone. Now we keep a list of X11 devices and try to match events to
them. On the Blender side there are still some limitations in regards to using
multiple devices at the same time, but this should improve things already.
Fixes T59645.
