evaluate: prepare to store expr key rather than datatype
currently set definitions store a datatype rather than an expression. In order to support use of unqualified data types (string in particular), this prepares implicit set definition helper to expect an expression instead of plain data type. This also has the advantage that we can use EXPR_CONCAT to retain the original expressions when key concatentation is used, e.g. 'meta iifname . tcp dport'. The netlink serialization code can use this info to store individual key lengths independently of data types. Would also allow later on to store the original names of the expressions, e.g. "ip daddr", in the kernel to support a future typeof keyword, e.g. 'type typeof(ip daddr)' instead of 'type ipv4_addr'.
