  [flang][PFT] record every target of multiway branches (#210012)

The Evaluation node stored branch targets in a single `Evaluation *`
(`controlSuccessor`). `markBranchTarget` therefore silently dropped
every target after the first when lowering a computed `GO TO` or
arithmetic `IF`, so any analysis that consulted `controlSuccessor` to
enumerate branch targets saw only the first label.

Add `extraControlSuccessors` alongside
`controlSuccessor`. `markBranchTarget` still fills `controlSuccessor`
with the first target, but appends each subsequent distinct target to
`extraControlSuccessors`. Extend the PFT dumper to print the extra
targets after the first ("-> N, M, K"), so PFT dumps expose every branch
target.
