Add 'custom-logo' to feature list API

[DannyCooper]

'custom-logo' is a valid theme tag, but it doesn't appear in the API - ​https://api.wordpress.org/themes/info/1.1/?action=feature_list

One consequence of this is that the "Theme Sniffer" reports it as an invalid tag - ​https://github.com/WPTRT/theme-sniffer

[DannyCooper]

Two more valid tags that aren't present: 'block-styles' and 'wide-blocks'.

API Commit: ​https://meta.trac.wordpress.org/changeset/8273

Before the wide-blocks (3 themes) and block-styles (4 themes) tags can be returned for WordPress, Core needs to be updated to add the translation/label here:
https://core.trac.wordpress.org/browser/trunk/src/wp-admin/includes/theme.php#L250

I've set the API to return them for WordPress 5.2+, assuming that the translations/labels can be added in trunk. If it gets backported into 5.1.x we can update the API as such, but I'm hopeful there'll be more than a handful of themes in those tags before Core supports it, as it's not a nice user-experience landing on a nearly-empty tag.

custom-logo is now being returned for WordPress >= 4.6.

And requesting https://api.wordpress.org/themes/info/1.1/?action=feature_list (or preferably, ​https://api.wordpress.org/themes/info/1.2/?action=feature_list) will return those new tags regardless of core support.

Thanks @dd32!

This has been implemented, right? So the ticket can be closed. If we'll need new ones, we'll open a new ticket :)

If I missed something feel free to reopen it.
