widl: Allow using UDTs with the keyword even when the identifier is also a typedef.

E.g. in cases like

    typedef int apple;
    struct apple { ... };

allow subsequently using "struct apple" in future expressions.
Note that this already worked for UDT definitions (so the above example by
itself was legal in widl), but any attempt to use the defined type would result
in a syntax error.
