Remove the stack map registry.

Browse Source 
This commit removes the stack map registry and instead uses the existing
information from the store's module registry to lookup stack maps.

A trait is now used to pass the lookup context to the runtime, implemented by
`Store` to do the lookup.

With this change, module registration in `Store` is now entirely limited to
inserting the module into the module registry.
