We want to enable gaining access to the underlying resource(s) by
inspecting a QRhiRenderTarget. This is not currently possible for
swapchains since there is nothing that references the actual
QRhiSwapChain. To clean this up, make an explicit, new
QRhiSwapChainRenderTarget subclass. Thus the logic already used in a
couple of places to examine the resources attached to a
QRhiTextureRenderTarget can now work with swapchain render targets too,
by branching based on the resourceType().
This eliminates the somewhat odd setup where a "RenderTarget" resource
is QRhiRenderTarget corresponding (but not exposing!) a swapchain,
whereas a "TextureRenderTarget" is a QRhiTextureRenderTarget which
is a subclass of QRhiRenderTarget. Now we correctly have an (abstract)
base and two subclasses, one for each type of render targets.
Besides, it allows us to clean up the oddly named
Q...ReferenceRenderTarget classes in the backends, which initially tried
to indicate that this "render target" merely references (or, in
practice, is) a swapchain. We can now have a nice and symmetrical
Q...SwapChainRenderTarget and Q...TextureRenderTarget naming scheme.

A further optimization would be to make the initial value of

The QPlatformBackingStore::scroll() API takes a QRegion as input, and we
kept this data type in the implementation of QCALayerBackingStore::scroll
for the logic of figuring out whether we could use the existing back
buffer as source of the scroll or if we needed to pull data from the
front buffer.
We then iterated the rects of the resulting in-line region, and called
qt_scrollRectInImage for each of them. This will unfortunately not work
whenever the scroll of one of these rects ends up overwriting parts of
the back buffer that later rects of the region use as their source rect.
This could be reproduced by moving the cursor within a text document,
which would dirty a small area around the cursor, making the subsequent
scroll of the viewport result in garbled text.
This issue exists in the other platform backingstore implementations
too, but since the QWidgetRepaintManager never calls scroll() with
anything but a single rect they would not have any issues.
The problem could potentially be solved by sorting the rects before
blitting them, but now this quick fix solves the regression on macOS.
