[EI-397] Separate fungible asset and token indexing

[rtso]

Description

Index fungible assets and tokens independently, to better reflect the composable nature of the object model on chain

1. Add fungible-related columns maximum_v2 and supply_v2 to fungible_asset_metadata (copied from current_token_datas_v2 )
   1. For coins, these fields will be null
2. Set to null fungible-related columns maximum, supply, decimals from token_datas_v2
   1. The only place that tracks fungibility of a token will be in current_token_datas_v2.is_fungible_v2
3. Set to null these columns since we can use a join to get the same information.
   • fungible_asset_metadata.is_token_v2
   • token_activities_v2.is_fungible_v2
   • current_token_ownerships_v2.is_fungible_v2
   • token_ownerships_v2.is_fungible_v2

Test plan

Run move scripts to create token mint, transfer, burn txn's. Run token_v2_processor and fungile_asset_processor on the txn's.

Mint fungible token

https://explorer.aptoslabs.com/txn/1033408820/userTxnOverview?network=testnet

Token tables

Fungible asset tables

Joins

Transfer fungible token

https://explorer.aptoslabs.com/txn/1033409449?network=testnet
Token tables had no change.

Fungible asset tables

FA balance changed.

Joins

Burn fungible asset

https://explorer.aptoslabs.com/txn/1033409890?network=testnet
Token tables had no change.

EI-397 Re index fungible tokens - new schema

[bowenyang007]

yea looks good. a few questions about setting the deprecated fields to null always but overall nice clean up!
