rhi: Make it safe to always call deleteLater on a resource

Browse Source 
...even when the QRhi is already gone. This should not happen in
well-written applications and libraries, but we handle this
gracefully in the regular dtor and destroy() for resources that
register themselves to their creator QRhi, so by registering
everything we can offer this to all QRhiResource subclasses.

We still want to differentiate between native resource owning
QRhiResources and others (that do not create native graphics
objects), so do this via a flag passed to registerResource().
This way the behavior with QT_RHI_LEAK_CHECK=1 does not change.

Pick-to: 6.5
