fix(rust/cardano-blockchain-types): fix CIP36

[bkioshn]

Description

• Improve CIP36 error handling
  • Error besides from decoding the CBOR should be accumulate into a record and return all errors.
• Remove decode_helper.rs and use cbor-utils
• Move cip36 folder to be under metadata
• Modify Cip36 constructor (new) to accept MultiEraBlock, txn_idx, and is_catalyst_strict, all the logic needed to construct Cip36 is implemented here instead of in cardano-chain-follower
• Cip36 struct now contains validation field.

Can we move cip36 into a metadata/cip36 module instead of at the root of the types. This is because we are likely to add more decoded metadata handlers and we should structure that more logically. It does not belong under auxdata because thats raw aux data whereas this is decoded metadata which uses it.
