src: add initial support for single executable applications

Rodrigo Muino Tomonari requested to merge github/fork/RaisinTen/add-initial-support-for-single-executable-applications into main

Compile a JavaScript file into a single executable application:

$ echo 'console.log(`Hello, ${process.argv[2]}!`);' > hello.js

$ cp $(command -v node) hello

# On systems other than macOS:
$ npx postject hello NODE_JS_CODE hello.js \
    --sentinel-fuse NODE_JS_FUSE_fce680ab2cc467b6e072b8b5df1996b2

# On macOS:
$ npx postject hello NODE_JS_CODE hello.js \
    --sentinel-fuse NODE_JS_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \
    --macho-segment-name NODE_JS

$ ./hello world
Hello, world!

It was decided in the Node.js Collaborator Summit that we want to come up with an MVP that is capable of compiling a single JavaScript file into a single executable application. More features will be added incrementally.
