Instead of hardcoding the command line parameters and the environment variables in the binary, pass them at runtime to Node.js and use the WASIp1 API to retrieve them in wasm_exec.js. The only real benefit right now is that it becomes possible to change `go.argv` and `go.env` before running a wasm binary. This also changes the syscall package for GOOS=js: it now becomes more like a libc (using wasi-libc), which means error values like `syscall.EEXIST` will actually match the one returned by the relevant libc function. Wasm binary size for packages that import the os package will be increased somewhat.
