wasm-ld: implement `--export-memory` flag
This flag allows the user to force export the memory to the host
environment. This is useful when the memory is imported from the
host but must also be exported. This is (currently) required
to pass the memory validation for runtimes when using threads.
In this future this may become an error instead.
