Auto merge of #7727 - michaelwu:update-bindings, r=jdm

Support the updated spidermonkey bindings

Still need to finish the rust-mozjs update and make cargo use it, but it's close enough that I don't expect much to change on the servo side.

Some changes here
- bools are properly translated now
- char16_t is handled as u16 now
- JS_GlobalObjectTraceHook isn't mangled now
- JSJitInfo has been adjusted
- A const fn is used to generate bitfields in JSJitInfo
- Manually generating handles now requires calling an unsafe function. It's not actually required, but it's too much of a hassle to generate them manually now due to bindgen++ adding base classes now.
