• Closes Add indexation AssetId -> (ContractId, SubId) #2425

• Related to Consider assets in check-account utility fuels-ts#3373

• It's based on top of Use indexation cache to satisfy "coins to spend" queries #2463 in order to have access to several mechanisms (like IndexationError) implemented previously for other indexes.

Description

This introduces a new GraphQL endpoint that returns info about an asset. Similarly to other indexes, the asset metadata index is only available when the client was started with no database and was able to sync from scratch. If the index is not available, this endpoint will return an error:

{
  "data": null,
  "errors": [
    {
      "message": "Asset metadata index is not available",
      "locations": [...],
    }
  ]
}

The off-chain worker indexes Mint and Burn events to store this metadata about an AssetId.
