Generic Registrar for ark-cli

[tareknaser]

Description

Currently, the index registrar is part of the ark-cli crate and uses a specific resource ID type. This is suboptimal.
We need to create a registrar that is generic over the resource ID type (which could be any of the ones defined in the dev-hash crate). This generic registrar should be moved to a separate crate and be available for use by any application, with ark-cli likely being the first to adopt it.

Challenges

The current implementation of the registrar uses the lazy_static! macro, which does not support generics. We'll need to refactor the code to address this.

Tasks

1. Refactor the registrar to be generic over the resource ID type.
2. Move the generic registrar to a new, separate crate.
3. Update ark-cli to use the new generic registrar.
