blink: Cleanup class/struct forward declarations

blink: Cleanup class/struct forward declarations

Remove useless class and struct forward declarations, and add
missing ones in blink header files. This is not the first time
such a cleanup is done for blink, but it should be the last as
we have now an up-and-running presubmit check.
