Stop calling Html::escape() for checkbox options

I'm sure this clean-up could be backported to 9.5

For role names escaping was added in #2560863: #options for radios and checkboxes uses SafeMarkup::checkPlain() to escape - use Html::escape() instead → other places in #2545972: Remove all code usages SafeMarkup::checkPlain() and rely more on Twig autoescaping →

The last submitted patch, 2: 3352972-2.patch, failed testing. View results →

Able to reproduce failures

- admin/structure/views/nojs/display/frontpage/page_1/display_title (set name to <em>Page</em> and save frontpage view
- admin/structure/views/nojs/display/frontpage/feed_1/displays should display escaped

Here's how it looks

@Lendude I'm sure it needs your approval and roles like displays can have names with markup

Tried testing on 11.x

Able to replicate the issue following #6
But after applying the patch issue still shows.
