[SuwLib] Implement tablet layouts

Implement suw_glif_*_template_card, and move the existing
implementation to suw_glif_*_template_content, which is included in
the card layout using <include>. Clients can use the common layout
by its old reference (e.g. suw_glif_list_template) since those are
aliased according to the respective screen sizes.
