[Temp][oz-wl] Media: Build VaapiPictureWayland as part of Media.

This is temporary, so we can avoid gl circular dependency. Eventually,
we want to be as aligned as possible with upstream Media solution and need
to figure out how we could use upstream VaapiWrapper (while able to generate
custom va_stubs if possible?).
