Remove HTMLHeadElement.profile

Remove HTMLHeadElement.profile
https://bugs.webkit.org/show_bug.cgi?id=249896

Reviewed by Ryosuke Niwa.

This patch is to align with Web-Specifications and other browser engines by removing 'profile' attribute support.

The patch removes "profile" attribute from 'head' element, which
was removed from HTML Specifications in 2010 and later dropped by browsers as
far back as 2014. Currently, only Safari / WebKit support this.
