  -----------
  [VPlan] Support scalable VFs in narrowInterleaveGroups. (#154842)

Update narrowInterleaveGroups to support scalable VFs. After the
transform, the vector loop will process a single iteration of the
original vector loop for fixed-width vectors and vscale iterations for
scalable vectors.
