Fixup binding generator for duplicate bindings.

When using multiple entry points it's possible for bindings to be
duplicated and existing in different binding type hashes. Currently this
would trigger an error in Tint as it would report a duplicate binding.

This CL changes the duplicate checking to allow duplicate entries as
long as the `src,dst` pair are the same. So, different entry points can
re-bindd the same source to the same dest without issue. This fixes up
the `tint` usage as it always remaps a binding to itself, so they are
always the same.

This does not effect Dawn as Dawn always runs the single entry point
transformation.
