Jakob Hellermann 7d9e864d9c implement Reflect for Input<T>, some misc improvements to reflect value derive (#5676)
# Objective

- I'm currently working on being able to call methods on reflect types (https://github.com/jakobhellermann/bevy_reflect_fns)
- for that, I'd like to add methods to the `Input<KeyCode>` resource (which I'm doing by registering type data)
- implementing `Reflect` is currently a requirement for having type data in the `TypeRegistry`

## Solution

- derive `Reflect` for `KeyCode` and `Input`
- uses `#[reflect_value]` for `Input`, since it's fields aren't supposed to be observable
- using reflect_value would need `Clone` bounds on `T`, but since all the methods (`.pressed` etc) already require `T: Copy`, I unified everything to requiring `Copy`
- add `Send + Sync + 'static` bounds, also required by reflect derive

## Unrelated improvements 
I can extract into a separate PR if needed.

- the `Reflect` derive would previously ignore `#[reflect_value]` and only accept `#[reflect_value()]` which was a bit confusing
- the generated code used `val.clone()` on a reference, which is fine if `val` impls `Clone`, but otherwise also compiles with a worse error message. Change to `std::clone::Clone::clone(val)` instead which gives a neat `T does not implement Clone` error
