[mlir][linalg] Add ods-gen helper to simplify the build methods.

Add a helper used to implement the build methods generated by ods-gen. The change reduces code size and compilation time since all structured op builders use the same build method. The change reduces the LinalgOps.cpp compilation time from 10.2s to 9.8s (debug build).

Depends On D123987
