Implement Debug for dynamic types (bevyengine#5948)

# Objective

When trying derive `Debug` for type that has `DynamicEnum` it wasn't possible, since neither of `DynamicEnum`, `DynamicTuple`, `DynamicVariant` or `DynamicArray` implements `Debug`.

## Solution

Implement Debug for those types, using `derive` macro

---

## Changelog

- `DynamicEnum`, `DynamicTuple`, `DynamicVariant` and `DynamicArray` now implements `Debug`
