Reviewed by Darin Adler.

Let Clipboard::types() return a ListHashSet<String> instead of a HashSet<String> to make sure
it retains the order in which type strings are added.

No test, this fixes an issue that was uncovered when lowering the default table size of WTF
hash tables, causing the HashSet<String> to rehash and reorder itself.
