Investigate additional necessary chain params/configuration for supporting SUI withdraw

[lumtis]

To perform withdraws the TSS must provide these two values:

• gateway object ID
• withdrawCap object ID

To do a whitelisting the following value:

• whitelistCap

WithdrawCap and whitelistCap IDs can be parsed in the gateway object, therefore only Gateway Object ID needs to be stored

Gateway object ID should be stored somewhere.

Considered options:

• In the gateway field of chain params: it will already contains the gateway package ID to allow parsing events, but it would be trivial to include a separator to include the gateway
  -> Drawback: field value is more "complex" and increase potential for mistake when setting the chain params

• Add a new field in the chain params to include this value
  -> Drawback: new field dedicated for Sui only

• Add the value as a ZetaClient config value
  -> There is no security risk associated with wrong value, a package ID is coupled with a gateway object ID, if wrong value is set TSS will not be able to perform withdraws
  -> Drawback: manual step for observers
