Reviewed by Tyler Wilcock.

This change assigns a generic ARIA role to <aside> elements when they are nested
within <aside>, <article>, <section>, or <nav> elements, aligning with the spec
(https://w3c.github.io/html-aam/#el-aside).
This follows the discussion in https://github.com/w3c/html-aam/issues/512

Additionally, it introduces a check to return LandmarkComplementary when an <aside>
tag has an explicit accessible name.
