 This doesn't seem to exist in WordPress Core and I haven't found a ticket
 asking about this. (I hope I haven't missed one, sorry if I did).

 `is_active_widget()` can't be used because all Block are added into the
 same Widget: `WP_Widget_Block`.

 For BuddyPress when migrating our Legacy Widgets to Widget Blocks, I had 2
 cases where some output wasn't made if a widget was active into a sidebar
 (Sitewide notice, and BP Primary Nav). To satisfy our need we are using
 [https://buddypress.trac.wordpress.org/browser/tags/9.0.0/src/bp-core/bp-
 core-template.php#L3869 this function] to check if a block or a widget is
 active into a Sidebar Widgets.

 I thought maybe it can be interested to have an equivalent of
 `is_active_widget()` into WordPress. I quickly put up a patch about it.
