Accessibility: Themes: use aria-current for the Walker_Nav_Menu current link.

Browse Source 
The `aria-current` attribute is a simple, effective way to help assistive
technologies users orientate themselves within a list of items. Continues the 
introduction in core of `aria-current` after [42440], [41683], [41359], and [41371].
