Add a createTextureFromId() alternative

Say hello to createTextureFromNativeObject(). This is the future
replaecment for createTextureFromId(), and is capable of operating
on both the direct OpenGL and the RHI code paths.

In practice this allows creating a QSGTexture that wraps - but does not
own - an existing VkImage, ID3D11Texture2D*, MTLTexture*, or GLuint.
