Generalize the logic used to convert column-vector ops to row-vectors to support converting chains of operations. A potential next step is to further generalize this to convert column-vector ops to row-vector ops in general, not just for operands of dot products. Dot-product handling would then be driven by the general conversion, rather than the other way around. PR: https://github.com/llvm/llvm-project/pull/72647
