[VPlan] Replace all uses of VF when EVL tail folding. NFCI (#146339)

Browse Source 
With EVL tail folding, any use of the VF live in should be replaced by
the EVL. Otherwise, it should likely be directly emitted as a constant
via VPTransformState::VF.

This strengthens the EVL transformation by replacing all uses of VF with
EVL and asserting that the only users are VPVectorEndPointerRecipe and
VPScalarIVStepsRecipe, the latter of which is new.

This should be NFC because even though we didn't previously replace the
EVL of VPScalarIVStepsRecipe, it's only used when unrolling which we
don't allow with EVL tail folding yet.
