Add QQuickWindow::TextureIsOpaque as option to createTextureFromImage.
Opaque textures can be a lot faster, so give this option without
forcing the user to reimplement her/his own QSGTexture class.
The old behavior was that createTextureFromImage() disregarded
TextureHasAlphaChannel and looked solely at the image's format. To
keep this behavior intact, we introduce a second opt-in flag to switch
textures from auto-detect to false, namely TextureIsOpaque.
[ChangeLog][QtQuick][QQuickWindow] Add TextureIsOpaque option to
createTextureFromImage()
