Implement a table to enable/disable features for specific chains

[lumtis]

Some features might not be immediately available for some chains.

Example: withdrawAndCall on Solana: #485

In general when the code is implemented for a new chain but not audited for mainnet, we might want to disable it at the smart contract level.

It would be useful to have a table allow to toggle these features per chain with an admin proposal, so we don't need to upgrade the contract each time which is a more sensitive action.
