Parse videopress media details

Atomic sites (maybe all sites with Jetpack Videopress enabled) returns a
`media_details` JSON object that is not compatible with the one in core.
That means the `parse_as_mime_type` function does not return
`VideoMediaDetails`.

We want to add a dedicated function to parse the `media_details` values
provide by the VideoPress plugin.
