Purpose
Remove V0 code path from the following models:
Please now that the model
phi4flashhas not been ported to V1 yet (#23996) and is non-trival to do so (requires porting differential attention backend). This PR removes the modeling code for that model. It can be re-added once the porting is done. The code will be useless until then anyway since V0 has been removed.Test Plan
Hybrid model test should verify nearly all of the above. I have run it locally. Let's see what happens in CI.
