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

• Could not deduce (ToJSON a0)

The type variable ‘a0’ is ambiguous
• In the ambiguity check for ‘Remove’
To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
