Widgets: Discount shortcodes and leading/trailing line breaks for triggering Text widget legacy mode.

Since shortcode handling is just-in-time deferred to run after `wpautop`, there is no need to retain the presence of shortcodes to trigger legacy mode. Also updates Text widget legacy mode notice informing of Custom HTML widget.

Merges [41070] onto 4.8 branch.
Amends [41050].
Props westonruter, melchoyce.
Fixes #40951 for 4.8.1.
