This removes the extra template file and uses the script to generate the whole nsCSSPropsGenerated.inc file directly, because it doesn't seem to really make much sense to have them separate. One behavior change to this refactor is that, the static assertions no longer include aliases. Other parts of the generated data all ignore aliases, so checking property id of aliases isn't really useful. It makes the code simpler everywhere to just strip aliases from the list at the very beginning. MozReview-Commit-ID: BYYvnCOqJwC
