Accessibility: Themes: Only unlink custom logo on the home page if the theme declares support for that.

Browse Source 
To accommodate for the change, the `custom-logo` theme feature now accepts the `unlink-homepage-logo` parameter.

If and when the logo is linked on the home page, the link has the `aria-current` attribute for better accessibility.

Follow-up to [48039], [48283].

Props sabernhardt, audrasjb, johnstonphilip, demetris.
Fixes #37011.
