[ABNF] Improve doc comment about bidi exclusions.

Browse Source 
This mentions embeddings and isolates besides overrides, in accordance with the
official terminology at https://www.unicode.org/reports/tr9/.

This update was discussed and agreed with @bendyarm.

Note: The Leo Reference includes text explaining these exclusions, with links to
the document above as well to the web site and paper about Trojan source
exploits.
