What was done:
* Removed headers in src/gui/accessible/windows/apisupport: as of
v13.1.0, MinGW supports most of the definitions in these headers.
Including uiautomation.h should be enough.
* Removed the QWindowsUiaWrapper class: it's not meant to be extended
or itself instantiated, is an "ultra-thin" layer (it even preserves
the "all-caps" Win types of function args), and is in effect only a
MinGW-bound "kludge". Instead of this class, use the UI Automation
API directly, with the assumption that it's available and fully
functional, as specified in the MS docs. Any gaps between this
assumption and what is delivered by MinGW are bridged with specific
(and explicit) temporary "kludges".
* Implemented said specific "kludges" in qwindowsuiautomation. For
Windows builds, the header just includes uiautomation.h, and the
.cpp is empty. For MinGW, the header contains definitions still
missing from uiautomation.h, and the .cpp implements functions
of the UI Automation core library through imports from the
uiautomationcore DLL.
* Windows plugins (and tst_qaccessibility): use the UI Automation API
definitions directly, instead of the "ultra-thin" wrapper.
* Windows plugin builds: use uiautomationcore library, if found.
What's intended:
* Unburden Gui of the Windows UI Automation COM interfaces and other
definitions that are copied in the uia*.h headers.
* Make the Windows plugins independent of MinGW shortcomings.
* Remove the QWindowsUiaWrapper class that essentially only hides these
shortcomings and the "kludge" code needed to overcome them.
* As MinGW adds further support to the UI Automation API over time,
make it noticeable which workarounds are no longer needed. The
current approach of hiding "kludges" in a wrapper class will also
hide the fact that they're no longer needed, if/when that time comes.

The problem occurred when we moved the cursor to the penultimate
character of the string, because the boundary condition was wrong. It
is important to realize that the offsets are moved *between* each
character (and also before and after the whole string), just like you
would move a cursor. This means that the offsets can be in the range
[0, len] (closed interval)
The problem could only be reproduced with JAWS.

Implement support for getting the strikethrough
style (UIA attribute UIA_StrikethroughStyleAttributeId [1])
by checking for the corresponding IAccessible2
text attribute "text-line-through-type" [2] and
mapping the value accordingly if set.
Only report those attributes from the
QAccessibleTextInterface::attributes return value,
if they apply for the whole range of the
QWindowsUiaTextRangeProvider.
With this in place, the NVDA screen reader on
Windows announces "strikethrough" as expected
when asked to report the formatting information
(e.g. via NVDA+f shortcut) for the QTBUG-118106 example.

This reverts commit 566def740ec58e842e6bb37177f80e20aebaa245.
The fix had some unwanted side-effects when the
QAccessibleValueChangeEvent carried a value of type string. Only
QComboBox uses QAccessibleValueChangeEvent in such a way.
The consequence of the reverted patch was that it broke QComboBox
so that the screen reader would read aloud the value change event
regardless of the visibility or focus state of the QComboBox. (Thus, if
you e.g. changed the QComboBox::currentIndex on a *hidden* combo box,
the screen reader would still read aloud the event)
This is also the root cause of what is described in QTBUG-93763.
Also, due to the usage of NotificationProcessing_ImportantMostRecent
the screen reader would treat it as such an important event that it
would abort whatever it was currently speaking.
In addition, the reverted change didn't fix any bugs and it failed to
implement the suggested behavior in a correct way (as was described in
QTBUG-75003 - albeit properly described after the change was merged).
QTBUG-75003 has already been reopened due to this, and the change can
therefore be reverted quite risk-free.

Support UIA's ISelectionProvider2 interface [1]
in addition to ISelectionProvider.
The ISelectionProvider2 interface inherits from the
ISelectionProvider interface.
A follow-up commit that will introduce bridging the
QAccessibleSelectionInterface, introduced in commit
9d16d5e2245c26e5746fd7609300b84a2a983457.
While at it, also reserve space for the amount
of children in the QList in QWindowsUiaSelectionProvider::GetSelection
before inserting them one by one, to avoid reallocations.
Sample use of the ISelectionProvider2 interface from NVDA's
Python console [2] with this commit in place:
1) start NVDA
2) run the gallery example (examples\widgets\gallery\gallery.exe)
3) click on the "Style" listbox at the top
4) press Numpad_insert+control+z to start the NVDA Python console and
capture snapshot variables
5) query and use the interface using NVDA's Python console
>>> import UIAHandler
>>> iselection2 = focus.parent.UIAElement.GetCurrentPattern(10034).QueryInterface(UIAHandler.IUIAutomationSelectionPattern2)
>>> iselection2.CurrentItemCount
1
>>> iselection2.CurrentFirstSelectedItem.CurrentName
'windowsvista'
>>> iselection2.CurrentLastSelectedItem.CurrentName
'windowsvista'

Remove the qmake project files for most of Qt.
Leave the qmake project files for examples, because we still test those
in the CI to ensure qmake does not regress.
Also leave the qmake project files for utils and other minor parts that
lack CMake project files.
