CW-1155 (and royalties extension)

[apolloshab]

This PR adds a basic implementation of ERC-1155 Multi Token Standard, along with the following extensions:

• On-Chain Royalties (based off CW-2981-Royalties)

References:

• ERC-1155
• ERC-1155 API

Some context on the history and current state of development: This PR continues where PR https://github.com/CosmWasm/cw-nfts/pull/78 left off. That implementation had most of the key parts of the standard implemented but was missing some things and required minor fixes to logic.

This PR includes the following additions to the previous implementation by ALPAC-4:

• On-Chain Royalties extension (based off cw2981).
• Send functions will pass along native funds sent along with the message to the recipient.
• Execute MintBatch: mint a batch of tokens.
• Execute Approve/Revoke: grant/revoke approval on specific tokens and token balances (from cw721).
• Query ContractInfo: query name/symbol of collection (from cw721).
• Query Ownership: query contract admin (from cw721).
• Query AllTokenInfo: query for paginated list of token infos (from cw721).
• Query Supply: query total number of tokens minted (from cw721).
• Refactors events to be in format {action}_single and {action}_batch. Batch events will also emit 1 event instead of multiple Single events.

Updates to cw721:

• generic parameter TQueryExtensionMsg added to Cw721Contract and relevant traits to handle query extension message
