rhi: Make sure pixelSize() to a texture rt is always up to date
This is an issue for QQuickWindow in practice, although it is not hit by our current tests. Pick-to: 6.3 Change-Id: Ia73704c1af6a82b2689ce7b844d3b0eb9a17ec18 Reviewed-by: Christian Strømme <christian.stromme@qt.io>

+ With QRhiTextureRenderTarget the returned size is the size of the
+ associated attachments at the time of create(), in practice the size of the
+ first color attachment, or the depth/stencil buffer if there are no color
+ attachments. If the associated textures or renderbuffers are resized and
+ rebuilt afterwards, then pixelSize() performs an implicit call to create()
+ in order to rebuild the underlying data structures. This implicit check is
+ similar to what QRhiCommandBuffer::beginPass() does, and ensures that the
+ returned size is always up-to-date.
