TwentyTwentyOne: Add aria-controls attributes to primary sub-menu.

Browse Source 
On the Twenty Twenty-One theme, this changeset adds `aria-controls` attribute to sub-menu buttons and an `id` to the sub-menu wrapper for additional context on what is being expanded.

Props bschneidewind, audrasjb, anandraj346.
Fixes #62973.
