[Web] Fix dlink_enabled build

After changing the default visibility to hidden to avoid generating
thousands of import/export symbols (browsers have a hard limit of 10k),
explicitly setting visibility for "boundary functions" (i.e. wasm
callbacks called by JS via pointer) is required to ensure the function
can be retrieved via pointer from the function table.
