[1.0.rc-1] WithdrawableBalance Base Query Needs Feature Added + Missing Implementation

[daniel-wehbe]

Describe the bug
We have a new base query message called WithdrawableBalance:

  #[returns(::cosmwasm_std::BalanceResponse)]
    WithdrawableBalance { address: AndrAddr },
    #[returns(Vec<self::permissioning::PermissionInfo>)]

This query need to be under a withdraw feature (similar to module feature for example). Also cannot find its implementation along with the rest of the base queries.

The withdraw feature has been removed. See #321
