compiler: don't read known type, simplify Import::finalize_methods
With the current export format, if we already know the type, we don't
have to read and parse the definition.
We only use the finalizer in Import::finalize_methods, so make it a
local variable. To match Finalize_methods::type, only put struct
types into real_for_named.
