  Log Message:
  -----------
  [mlir][VectorOps] Don't fold extract chains that include dynamic indices (#68333)

This is not yet supported and previously led to a confusing crash where
an extract op with a kDynamic marker, but no dynamic positions was
created. The verifier has also been updated to check for this, and hint
at where the problem is likely to be.
