[w3c/screen-orientation] remove unused fullscreen element dependency (#191)

Goal is to remove the spec's [dependencies list](https://w3c.github.io/screen-orientation/#dependencies).

#### Dependencies
1. Fullscreen element - unused, removed in this PR
2. HTML list of the descendant browsing contexts - [PR to export the term. Has ongoing discussion](https://github.com/whatwg/html/pull/5194)
3. Page Visibility now visible algorithm - [issue to export page visibility definitions](https://github.com/w3c/page-visibility)
4. Animation frame task - the linked [issue](https://github.com/whatwg/fullscreen/issues/16) is still pending. There doesn't seem to be a way to link the definition through xref yet.
