[media] Use HasSharedImage instead of HasTextures in most callsites

Replace VideoFrame::HasTextures with HasSharedImage in most callsites
which create a VideoFrame with shared image instead of legacy mailbox.

Also remove an old mojo test that uses api that is no longer used
and update the other mojo test with correct api for creating video
frame.
