  [mlir][bufferization] Bufferize all edges to a repeated successor (#214368)

bufferizeBlockSignature only rewrote the first successor index that
matched the target block. Branch ops such as cf.cond_br can list the
same destination more than once, but the later edges were left as
tensors and broke multi-block bufferization.

Now we simply iterate the block's BlockOperands so each successor edge
is handled once.
