  [VPlan] Set branch weight metadata on middle term in VPlan (NFC) (#143035)

Manage branch weights for the BranchOnCond in the middle block in VPlan.
This requires updating VPInstruction to inherit from VPIRMetadata, which
in general makes sense as there are a number of opcodes that could take
metadata.

There are other branches (part of the skeleton) that also need branch
weights adding.
