Releases (or requests deferred releasing of) the underlying native graphics resources.
Safe to call multiple times, subsequent invocations will be a no-op then.
Once destroy() is called, the QRhiResource instance can be reused, by calling create()
again. That will then result in creating new native graphics resources underneath.
The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.

Valid only after create() has been called successfully. Until then the result is a default-constructed QSize.
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.
