fix: skip type check for address-index RPCs that accept polymorphic input

The address-index RPCs (getaddressbalance, getaddresstxids, getaddressdeltas,
getaddressutxos, getaddressmempool) declare their first parameter as ARR but
actually accept either a bare string (single address) or an object with an
addresses array. The stricter type checking from bitcoin#29277 now validates
parameter types before the handler runs, causing these RPCs to reject string
inputs with 'JSON value of type string is not of expected type array'.

Add skip_type_check to these RPCs since they intentionally handle polymorphic
input in getAddressesFromParams().
