This has been constantly mentioned as buggy and broken and there is no
official version of latin or Arabic (see the ticket for more details).
This can be turned back as an extension if needed by third party users.

Just methods where adding "static" to the declaration was enough, I
didn't do anything with providers that used $this.
Initially by search and replace. There were many mistakes which I
found mostly by running the PHPStorm inspection which searches for
$this usage in a static method. Later I used the PHPStorm "make static"
action which avoids the more obvious mistakes.

Allow Bcp47Code (which includes Language) as a parameter to
::getParentLanguage(), to match what was added in
Iea158fc849964ba71a27363f9522b1b3bbb82aee. Add a note to warn
callers that ::getParentLanguage() does *not* accept the same set
of string codes as ::getLanguage(); however if you pass an object
instead of a string the behavior matches.
