Implement more traits for FRTs

From https://github.com/rust-lang/rust/pull/154927#discussion_r3068460955.

FRTs now implement the following traits: `Sized + Freeze + RefUnwindSafe + Send + Sync + Unpin + UnsafeUnpin + UnwindSafe + Copy + Debug + Default + Eq + Hash + Ord`.

Let me know if there is any trait missing.

I also removed the explicit  `Send` and `Sync` impls, since commit cb37ee2c87 ("make field representing types invariant over the base type") made the auto-trait impl work even if `T: !Send` or `T: !Sync`. Very happy to see unsafe impls get dropped :)

Note that I used the reflection feature (cc @oli-obk) to print the actual field names in the debug implementation. I think this is a cool way to use it, but if it isn't ready for that, I'm happy to change it to the alternative implementation I gave in the note comment (it's essentially Mark's suggestion but printing `T`'s name instead of `Self`'s).

Since this is a library change, I'll give this to Mark; feel free to also take a look/leave comments, Oli :)
