CLI and networking support (#119)

### Description Adds support for CLI SAPI and networking in node.js: ``` > npm run build > node ./build-cli/php-cli.js -r 'echo "Hello from PHP !";' Hello from PHP ! > node ./build-cli/php-cli.js -r 'echo substr(file_get_contents("https://wordpress.org"), 0, 16);' <!DOCTYPE html> > node ./build-cli/php-cli.js -r 'echo phpversion();' 8.2.0-dev > PHP=5.6 node ./build-cli/php-cli.js -r 'echo phpversion();' 5.6.40 ``` ### Highlights: * Networking is supported (including MySQL and HTTPS) * Switching PHP versions is supported. * [Most WordPress PHPUnit tests pass](WordPress/wordpress-playground#111). The failures are caused by missing extensions and a few misconfigured settings * PHP Interactive mode is supported but [the arrow keys don't work](WordPress/wordpress-playground#118) * `wp-cli` works ### In broad strokes: * CLI SAPI is compiled with libedit (readline replacement) and ncurses. * Network calls are asynchronous. Emscripten's Asyncify enables calling asynchronous code from synchronous code. TCP sockets are shimmed with a WebSocket connection to a built-in proxy server running on localhost. It supports data transfer, arbitrary connection targets, and setting a few TCP socket options. * PHP's OpenSSL uses the same CA certs as Node.js * PHP 5.6 is patched to work with OpenSSL 1.1.0 and many other small patches are introduced. For more details, see [patches overview](WordPress/wordpress-playground#119 (comment)), Dockerfile, and `phpwasm-emscripten-library.js` ### Future work: * PHP Interactive server isn't supported yet. Adding support is a matter of making the incoming connection polling non-blocking using Asyncify. * Use a more recent OpenSSL version * [Better support for CLI interactive mode](WordPress/wordpress-playground#118)
