MetadataStorage is mutable - structural equals in copy isn't enough (#11513) 
`MetadataStorage` is mutable. Using `Object.equals` in `IR.copy` methods to check whether a _copy is needed_ isn't enough. The fact that two storages are `Object.equal` may be just temporary. Replacing the checks in 69 `IR.copy` methods with identity check - e.g. `ne` in Scala which is `==` in Java.

Using proper structural check inside of `MetadataStorage` fixes #11171.

# Important Notes
I [used this regex](https://github.com/enso-org/enso/issues/11171#issuecomment-2463908932) to find out 69 instances of `IR.copy`:

![69 copy methods](https://github.com/user-attachments/assets/257580b9-54fc-4199-88ad-a22103b0041f)

and I modified all 69 of them.

The Enso Engine

The Enso engine is the codebase responsible for compiling and executing Enso code, as well as providing language server functionality to users of the language. It is subdivided into two major components:

  • Language Server: The Enso language service.
  • Polyglot API: The truffle-boundary safe API for communication between the language server and the runtime.
  • Runner: The command-line interface for Enso.
  • Runtime: The compiler and interpreter for Enso.
