This adds support for serialization of `WasmEHFuncInfo`, in the form of <Source BB Number, Unwind destination BB number>. To make YAML mapping work, we needed to make a copy of the existing `SrcToUnwindDest` map within `yaml::WebAssemblyMachineFunctionInfo`. It was hard to add EH MIR tests for CFGStackify because `WasmEHFuncInfo` could not be read from test MIR files. This adds the serialization support for that to make EH MIR tests easier.
