Change interface conflict stub to take the interface method.

To avoid doing dex cache lookup, pass the interface method instead. This
costs a few hundred KBs on speed compiled APKs (< 0.5% code size), but
improves performance when hitting a conflict (as seen on dogfood data).

For nterp, we currently pass the conflict method instead of the
interface method. We need to handle default methods before optimizing
it.

This removes our last use of dex cache in compiled code. A follow-up CL
will remove the NeedsDexCacheOfDeclaringClass from HInvokeInterface.

Test: test.py
