[AIP-43][Discussion] Parallelize Digital Assets (Token V2) and Fungible Assets minting/burning

[igor-aptos]

AIP Discussion

Change Token V2 and fungible assets minting and burning to be parallelizable during execution, allowing higher throughput/peak for minting from an individual collection / asset.

Introducing new mint API - create_numbered_token, which will allow creating tokens in parallel, from the same collection, while providing sequential names.

Motivation

Currently, Token V2 minting and burning within a single collection is single-threaded, because those operations do read-modify-write on multiple per-collection fields - current_supply, total_supply and sequence number in the event handles. That translates into minting from a single collection having 5-8x lower throughput than minting from multiple collections simultaneously.

Similarly, minting and burning Fungible Asset touch supply field, making them sequential.

Goal is to remove/optimize operations that make Token V2 and Fungible Asset operations sequential
