NinePatchImage: support the compressed texture image

The compressed texture image is supported by qquickimage and
the qquickninepatchimage is inherited by qquickimage.
But the compressed texture is not shown when the source of
qquickninepatchimage is set as compressed texture because the
updatePaintNode of qquickninepatchimage only consider non-compressed
texture.

This patch is not intended to use the HW compressed image as an
actual 9-patch image, but to display them using the super class
qquickimage in the case of an HW compressed image other than a normal
pixmap image.

If the source is HW compressed textures such as ASTC, KTX, and PKM,
we have to call updatePaintNode of QQuickImage before checking the
validity of the pixmap image.
(because nullptr is returned if pixmap image is not valid)

The containers themselves (pkm, ktx) are universally supported but
the compressed texture formats is up to the underlying 3D API
implementation and may vary.
So, if the format is not supported by RHI, we skip the test.
Refer to QTBUG-113565 for a detailed discussion on texture formats.

And when using the software backend, we also skip test cases.
