feat(devnet): runtime non-fungible pallet (basic standard features)

[chungquantin]

Runtime first implementation of the local non-fungible use case. Deliverables include:

• Pallet non-fungibles implementation following the spec feat: local non-fungible use cases #259 to provide both read and write methods.
• Mock runtime configuration and unit testing.

Important

Questionable approach in the allowance method that currently forks the relevant structs to ItemDetail. The purpose of this is to get the field approvals (which is a private field in a private struct ItemDetail) by decoding.

Note

Will need to design this API to be compatible with v1.14.0 in main, currently v1.7.0 in daan/api
