WM_POINTERLEAVE occurs when the pen goes out of range or when a
hovering pen leaves the window's boundary. When leaving the window
boundary the xy position is invalid for some Wacom devices.
This change removes creation of GHOST_EventCursor during
WM_POINTERLEAVE events. This prevents unexpected jumping behavior
during continuous grab.
Previously Wintab was handled by saving the most recent tablet pressure and tilt information and deferred appending tablet infromation to Windows mouse events. This caused synchronization issues evident at the beginning and ending of strokes where pressure and tilt were either ahead or behind in time from mouse button up or down events. This also dicarded swaths of data which resulted in blockly grease pencil lines most apparent when a context switch resulted in several coalesced mouse events.
This patch changes the behavior of Wintab to instead rely entirely on Wintab information for pressure, tilt, position, and button input.
Wintab has several design decisions and conventions which complicate relying soley on it's input while retaining current workflows reliant on non-API behavior. For example, many device optionally allow the user to map barrel buttons to non-mouse actions. These mappings may or may not modify the intended behavior when touching the stylus down, such as scroll vs alt mappings. This behavior is not exposed in the Wintab API, but Wintab will continue updating button state sans this necessary context.
To work around the problem, this refactor synchronizations tablet input to Windows mouse down and up events, this captures events which should result in pen input while allowing events such as pen scrolling. Until a Windows mouse down event fires Wintab input is left unprocessed; when a Windows up event occurs Wintab is processed until a corresponding button up event is found.
Wintab allows for either button state or changes to be reported, but not both. An earlier refactor tried to use button changes to let state to be managed by Wintab. This was replaced when it was found that button change events were unreliable at corner cases such as switching windows. It was also found that with Wacom drivers Wintab peek functions would modify events in the queue causing errant and loss of button events.
For the latter stated reason this patch opts to read all Wintab events into a queue as they arrive, removing events as they become stale. This was chosen over using Wintab peek functions due to the afformentioned issue. As a bonus this seems to work better as it prevents the queue in Wintab from filling, thus neither a flood of events need to be handled when Wintab processing begins and a Wintab implementation need not be trusted to overwrite old events in it's queue.

events until one is found. This prevents errant cursor moves that occur
before the Wintab button event is reported. We need to skip these events
because if no button event exists, we generate one assuming it will either
arrive later in the Wintab queue or that the button was from a non-Wintab
device. For the case that this was generated by a non-wintab device, such
as buttons mapped to mouse on the tablet pad, these cursor move events can
significantly move the cursor from the intended click position.

Don't use the current mouse position at the time the event is handled, but
rather the position at the time of the event. This should make e.g. brush
stroke paths more accurate.
In addition, this may solve issues with other software that does mouse
position smoothing. Ref T82143.
Use of the current mouse position was added in 12b642062c as part of a
large commit that also made continuous grab work. But it appears to still
work getting the mouse position from the event.

We need a separate time stamp for each axis, and we have to add a few
milliseconds of padding to those, to ensure wrapping on both axes get
properly performed when it happens almost simultaneously, and avoid
extra wrapping caused by very close events sometimes.

Now Wintab is not initialized when starting Blender with the tablet API
preference set to native, since that disables Windows Ink.
Note that changing the tablet API requires restarting Blender for changes
to take effect. This serves as a stopgap to allow use of Windows Ink until
runtime API switching is merged.

When Blender is started in fullscreen mode from the command line,
or if the fullscreen state is saved in the startup file, all temporary windows
will also open in fullscreen mode. When closing the fullscreen File Browser,
Blender would either crash or parent window becomes black.
This does not happen if the Blender switches to full screen manually.
`NSWindowCollectionBehaviorFullScreenPrimary` should be set for windows that
can enter full-screen mode. Otherwise macOS will turn the wrong window into
full-screen.
