Regenerate bindings.

The oldest commit is from #14220 which hasn't merged yet.  The second commit is the update for the sync: https://treeherder.mozilla.org/#/jobs?repo=stylo&revision=88d68e17f03c1f8b9f688081902a3369ea83e627

The newest commit is just regenerating bindings again with an updated rust-bindgen (since the previous few bindings updates were done with an old rust-bindgen).

I ran `./mach test-stylo` and all the tests pass.
