Otherwise we can duplicate linker flags across input binaries, which can result in very large linkerr invocation commands.

This change adds support for `.swift1_autolink_entries` in WebAssembly object files to `lib/DriverTool/autolink_extract_main.cpp`. This is implemented in a similar way to existing ELF autolink entries handling.
