Add job for testing ABI stability across builds

The idea is that both the bindists should product libraries with the
same ABI. So the job checks with ghc-pkg to make sure the computed ABI
is the same.

In future this job can be extended to check for the other facets of
interface determinism.

Fixes #22180
