avcodec/libvpxenc: add VP9 temporal scalability encoding option

Browse Source 
This commit reuses the configuration options for VP8 that enables
temporal scalability for VP9. It also adds a way to enable three
preset temporal structures (refer to the documentation for more
detail) that can be used in offline encoding.
