We plan to enable multivalue in the features section soon (#80923) for other reasons, such as the feature having been standardized for many years and other features being developed (e.g. EH) depending on it. This is separate from enabling Clang experimental multivalue ABI (`-Xclang -target-abi -Xclang experimental-mv`), but it turned out we generate some multivalue code in the backend as well if it is enabled in the features section. Given that our backend multivalue generation still has not been much used nor tested, and enabling the feature in the features section can be a separate decision from how much multialue (including none) we decide to generate for now, I'd like to temporarily disable the actual generation of multivalue in our backend. To do that, this adds an internal flag `-wasm-emit-multivalue` that defaults to false. All our existing multivalue tests can use this to test multivalue code. This flag can be removed later when we are confident the multivalue generation is well tested.
