Subject: [PATCH] HTML API: Add support for IN SELECT IN TABLE parsing.

As part of work to add more spec support to the HTML API, this patch adds
support for the IN SELECT IN TABLE insertion mode. This small section of the
spec handles rules for the `<select>` element and its children when found
inside of a `<table>`.

Developed in https://github.com/wordpress/wordpress-develop/pull/7044
Discussed in https://core.trac.wordpress.org/ticket/61576

Props: dmsnell, jonsurrell.
See #61576.

Built from https://develop.svn.wordpress.org/trunk@58841
