Bootstrap block bindings sources earlier in the process through an inline script to ensure they are available when developers want to extend them in the client. Following the same pattern other APIs like registering block types are doing. Props santosguillamot, cbravobernal, gziolo. Fixes #6225. Built from https://develop.svn.wordpress.org/trunk@59238 git-svn-id: http://core.svn.wordpress.org/trunk@58630 1a063a9b-81f0-0310-95a4-ce76da25c4cd
