QPageSize: mark ctors explicit

A QSize or QSizeF is not an accurate representation of a QPageSize, so
the corresponding constructor should be explicit.

Many setters check for an actual change before making changes to

QPageLayout: clean up operator==

The old code always compared the Private classes, unless one of them
was nullptr (which it never was, as there is no move ctor and all
other ctors create a QPageLayoutPrivate.

The new code compares the dpointers, and only if they differ, the
Private classes. It also drops the nullptr checks, as they cannot
trigger.

XCB: Only use the XFixes extension if available

Commit 0d4918950e61f added a new place
(QXcbWindow::setTransparentForMouseEvents()) where requests from the
XFixes extension are generated. However, this wasn't checking if the
extension is actually supported before using it.

Fix this by turning QXcbWindow::setTransparentForMouseEvents() into a
no-op if the XFixes extension isn't available.

This means that the window in question won't be transparent for mouse
events, but we cannot do much about that if the X server doesn't support
the required extension.

Accessibility Mac: Cache Accessible Elements and Notify about changes

The big change is that we now keep the id objects representing accessibles
around so that they are persistent for ATs.
This improves performance of Mac accessibility significantly.

This is required for notifications which are now sent so that many things work much better,
for example the VoiceOver focus follows the keyboard focus.

The parent element in QCocoaAccessibleElement was removed, we can
dynamically access it more reliably.
