Disable the scrolling optimization in QBackingStore
and fall back to repainting for non-integer deltas.
The existing rendered pixels are not re-usable in
this case.
The test is made on the delta, and not on the scale
factor. This means that user code can cooperate and
generate (logical delta, scale factor) combinations
that result in integer pixel deltas (which _can_ be
scrolled).

This reverts commit 13040043b2.
It introduced a bad regression, noticeable for longer documents, as
it would cause the documentChanged(0, length) to trigger a layout of
the entire document.
The bug report for the commit (or the commit itself) does not contain
a test case, but it is regardless the wrong approach. Note that
QQuickTextEdit already listens to the contentsChange signal and
invalidates the changed parts of the document as a reaction to this,
so it should already work as expected.

In some auto-tests, we create several instances of
QGuiApplication (though seldom, if ever, simultaneously).
However, the QCocoaMenuLoader instance was never properly
deallocated, resulting in NSApplication.servicesMenu
to still be assigned. This resulted in an exception being
raised (NSInternalInconsistencyException) the second time
we would construct a QCocoaMenuLoader.
The CPU cycles saving solution is to make QCocoaMenuLoader
a singleton. This approach is also safe since this class'
initialization doesn't depend on any state in QGuiApplication
(even the application name is fetched from either the main
bundle or the app's args).
This also allows us to clean up some code in QCocoaApplication
and QCocoaApplicationDelegate who have suffered from lack of
attention over the years.

Change e109b8a0f3 introduced a
performance regression when rapidly switching fonts as long as
the number of different fonts is over a relatively small number, since
the cost of fonts can be high compared to the limits set on the cache.
Since the original patch was intended to avoid exceeding the
open file limit when using Freetype on Windows, we add an
additional check on the number of engines in the cache as well
for the added, synchronous cache flush.
The limit is set to 256 to make it unlikely that it is exceeded
during a single paint event, but it can also be configured when
building Qt if a higher limit is needed.
