Message:

Bundled theme: Add preconnect to fonts.gstatic.com in 2012-15 themes.

Add preconnect hinting for https://fonts.gstatic.com in the bundled themes using Google fonts. WordPress versions 4.7+ include a crossorigin attribute, earlier versions will not.

Props leobaiano, swissspidy, peterwilsoncc.
Fixes #37171.
