misc/wasm: add scripts for running WebAssembly binaries This commit adds scripts for running the WebAssembly binaries that the Go compiler will produce. The script go_js_wasm_exec uses Node.js to run the binaries. Adding it to PATH will enable "go run" and "go test" to work for js/wasm without having to manually provide the -exec flag. See https://golang.org/cmd/go/#hdr-Compile_and_run_Go_program for more information. The web page wasm_exec.html is an example on how to run the same binaries in a web browser. Both scripts use wasm_exec.js as a shared library.

misc/wasm: expect environment to provide polyfills The list of environments to support with wasm_exec.js was becoming too large to maintain. With this change, wasm_exec.js expects that the environment provides all necessary polyfills. The standardized "globalThis" is used for accessing the environment. wasm_exec.js now only provides stub fallbacks for globalThis.fs and globalThis.process. All code specific to Node.js is now in a separate file.
