  [VPlan] Version VPValue names in VPSlotTracker.  (#81411)

This patch restructures the way names for printing VPValues are handled.
It moves the logic to generate names for printing to VPSlotTracker.

VPSlotTracker will now version names of the same underlying value if it
is used by multiple VPValues, by adding a .V suffix to the name.

This fixes cases where at the moment the same name is printed for
different VPValues.
