register missing reflect types (#5747)

# Objective

- While generating https:/jakobhellermann/bevy_reflect_ts_type_export/blob/main/generated/types.ts, I noticed that some types that implement `Reflect` did not register themselves
- `Viewport` isn't reflect but can be (there's a TODO)


## Solution

- register all reflected types
- derive `Reflect` for `Viewport`


## Changelog
- more types are not registered in the type registry
- remove `Serialize`, `Deserialize` impls from `Viewport`


I also decided to remove the `Serialize, Deserialize` from the `Viewport`, since they were (AFAIK) only used for reflection, which now is done without serde. So this is technically a breaking change for people who relied on that impl directly.
Personally I don't think that every bevy type should implement `Serialize, Deserialize`, as that would lead to a ton of code generation that mostly isn't necessary because we can do the same with `Reflect`, but if this is deemed controversial I can remove it from this PR.

## Migration Guide
- `KeyCode` now implements `Reflect` not as `reflect_value`, but with proper struct reflection. The `Serialize` and `Deserialize` impls were removed, now that they are no longer required for scene serialization.
