Docs: rename "Screen readers" helper page to "Visually hidden"

"screen readers" is quite reductive, as there are other assistive technologies. content hidden this way is even announced by things like Alexa/Siri etc, so it's not so much just "screen readers".
in the long run, we may even consider changing the actual classnames (maybe `.visually-hidden` / `.visually-hidden-focusable`, though admittedly that's a bit verbose).

also includes a tiny tweak to layout.md to generalise the note about using `.sr-only`

Docs: separate button group out of checks/radios, expand button groups page (#31201)

* Keep checks/radio toggle buttons on topic

- give examples of the pure toggle checks and radios, without the button group class. show that these work fine without `.btn-group`, but still cross-reference it
- move the explanation from "Checkbox toggle buttons" directly to "Toggle buttons", as the mention of using button classes applies equally to the subsequent "Radio toggle buttons" and "Outlined styles" subsections.

* Expand button group description

as it's not just single line, but vertical as well

* Expand button group examples

- add more colour ... `.btn-secondary` is just dull and uninspiring
- new section to showcase "Checkbox and radio button groups"
- add a mixed styles example
- add an example of vertical radio button group

- make the disabled toggle example using a link actually follow the preceding advice of also having `tabindex="-1"` and `aria-disabled="true"`
- tweak the link functionality callout to also still mention `aria-disabled` to reinforce the idea
- tweak toggle state description (not just `<button>`s, but also links etc...so just remove mention of `<button>` there; also reinforce accessibility aspect once more)
- add a new callout that cross-references checkbox-based toggles, and what the similarity/difference between them is
- add a matching cross-reference callout to the checkbox-based toggle buttons page
