layouts/partials: Override internal templates for page bundles

Browse Source 
The Hugo internal Twitter and OpenGraph templates assume your post
images are in the static directory. This tries to look them up in
the page bundle first and falls back to the Hugo default behavior.

<!--
Import Hugo's internal twitter_cards.html template to add support for resolving
images in page bundles and with falling back to the default of looking in the
static assets directory.
See: tpl/tplimpl/embedded/templates/twitter_cards.html
