pretty-print: support URL escape sequences (PR 87488)
https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda
describes an emerging standard for embedding URLs in escape sequences
for marking up text output. This is supported e.g. by recent releases
of GNOME Terminal.
This patch adds support to our pretty-printing framework for emitting
URLs.
A followup patch uses this to add URLs to the pertinent documentation
for the output of -fdiagnostics-show-option.
