Editor: Introduce WP_Block and WP_Block_List classes
Backports functionality added in Gutenberg in the following PRs: - https://github.com/WordPress/gutenberg/pull/21467 - https://github.com/WordPress/gutenberg/pull/21925 It's a few ideas related to block rendering and the provided block value, which is particularly impactful for work around block context. Props aduth, TimothyBJacobs, noisysocks, epiqueras, youknowriad, talldanwp, zebulan. Fixes #49926. Built from https://develop.svn.wordpress.org/trunk@48159 git-svn-id: http://core.svn.wordpress.org/trunk@47928 1a063a9b-81f0-0310-95a4-ce76da25c4cd
