Subject: rust: page: Add support for vmalloc_to_page

This series aims to add support for pages that are not allocated by an instance of the Page
abstraction, specifically those returned by vmalloc_to_page().

This patch series is sent in the context of developing a Nova driver WIP feature where we
load the the GSP firmware into an sg table [1].
