Windows QPA: Further cleanup of pre-Win10 code

Mostly a removal of dynamically loaded Win32 APIs.
Since Qt 6's minimum supported platform is Win10 1809
(10.0.17763, code name RS5), all these functions will
be available and no need to resolve them at run-time.

Things not remove:
WinTab functions in "qwindowstabletsupport.cpp".
Not my familiar area, so not touch it.

Pick-to: 6.2
Task-number: QTBUG-84432
Change-Id: I7ad6c3bc8376f6c0e3ac90f34e22f7628efeb694
