Media queries: Update selection API to support media queries.

The API changes are:

1.  When building a selection context, stylesheets added with
    `css_select_ctx_{append|insert}_sheet()` now have to have
    media strings associcated with them.  Previously they took
    a simple bitfield for CSS media type.

2.  When selecting for an element, the client needs to specify
    the current media requirements.  Previously it only had to
    provide the bitfield for CSS media type.

3.  Same for the css_select_font_faces API.

The selection handling has been updated to handle the new
API, however it is currently only looking at the media type
when performing selection.
