Subject: [wasm-split] Add an option to emit only the module names (#3901)

Even when other names are stripped, it can be useful for wasm-split to preserve
the module name so that the split modules can be differentiated in stack traces.
Adding this option to wasm-split requires adding similar options to ModuleWriter
and WasmBinaryWriter.
