Nix error messages gig

Nix error messaging improvements

The goal is to improve beginner experience in Nix.

1. Create github.com/NixOS/nix-message-catalog

Go through Nix issues, move those related to error messages in our new repo.

2. Display the snippet of code where the error happened based on the source position

The type variable ‘a0’ is ambiguous
• In the ambiguity check for ‘Remove’
To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
In the definition of data constructor ‘Remove’
In the data type declaration for ‘Operation’
