Add COMPILE_ASSERT to ensure the result of Bind matches the Callback's type.
Required because we abstract the storage of the funciton pointer out using
a reinterpret_cast to reduce template bloat. This effectively readds the
failure that would have happened had we stored the function pointer directly
in the template class.
BUG=86008
TEST=new unittests.
