QPlatformBackingStore: don't hold QBackingstoreTextureInfo in QList

QBackingstoreTextureInfo is larger than a void*, so holding them in
a QList is needlessly inefficient. Worse, the code could come to
depend on the fragile property of (inefficient) QLists that
references to elements therein never are invalidated.
