Message:

Twenty Seventeen: Remove IE specific resources.

This changeset switches the wp_enqueue_* functions to wp_register_* for IE-related resources, which maintains handles, source references, etc., keeps all
IE-specific files within the theme package to avoid errors, and requires site admins to opt in to loading them in the theme.

It also replace the content of html5.js shiv with a comment (to avoid 404s) and removes IE-specific code in general stylesheets.

Props desrosj, sabernhardt, audrasjb, neychok, oglekler.
See #56699.
