Use task dialogs even for the dialogs with wxPD_AUTO_HIDE style flag and
without wxPD_CAN_ABORT one. Generic fallback was used in this case as native
task dialog doesn't support dialogs without buttons but it is finally better
to create a dummy button and use the native dialog nevertheless. We already
have a mostly disabled "Close" button for the dialogs without wxPD_AUTO_HIDE
style so it seems logical to also have it (but just never enable it at all)
when this style is used.
Closes#12462.

If available, the task dialog is now used for the wxProgressDialog under
Windows. This provides a much more native looking dialog which doesn't look
out of place under modern Windows versions, unlike the generic implementation.
The internals of the code had to be significantly changed as the task dialog
can only be shown modally so, to emulate wxProgressDialog modeless nature, a
separate thread is used for the progress dialog management.
