Objective

• Follow-up on some changes in Move EntityHash related types into bevy_ecs #11498
• Unblock using Identifier to replace ComponentId internals.

Solution

• Implement the same Reflect impls from Entity onto Identifier as they share same/similar purposes,

Testing

• No compile errors. Currently Identifier has no serialization impls, so there's no need to test a serialization/deserialization roundtrip to ensure correctness.

Changelog

Added

• Reflection implementations on Identifier.
