  Log Message:
  -----------
  [VPlan] Iterate over VPlans to get VFs to compute cost for (NFCI).

Instead for iterating over all VFs when computing costs, simply iterate
over the VFs available in the created VPlans.

Split off from https://github.com/llvm/llvm-project/pull/92555.

This also prepares for moving the check if any vector instructions will
be generated to be based on VPlan, to unblock recommitting
https://github.com/llvm/llvm-project/pull/92555.
