Message:

Widgets: Add shortcode support inside Text widgets.

• Used now in core to facilitate displaying inserted media. See #40854.
• The [embed] shortcode is not supported because there is no post context for caching oEmbed responses. This depends on #34115.
• Add do_shortcode() to the widget_text_content filter in the same way it is added for the_content at priority 11, with shortcode_unautop() called at priority 10 after wpautop().
• For Text widget in legacy mode, manually apply do_shortcode() (and shortcode_unautop() if auto-paragraph checked) if the core-added widget_text_content filter remains, unless a plugin added do_shortcode() to widget_text to prevent applying shortcodes twice.
• Ensure that global $post is null while filters apply in the Text widget so shortcode handlers won't run with unexpected contexts.

Props westonruter, nacin, aaroncampbell.
See #40854, #34115.
Fixes #10457.
