Improve Frida util: Use frida-compiler for code generation

[bernhste]

At the moment, the JavaScript used to intercept API is relatively simple. The demos use a run.sh script which concatenates the hook.js into the base script. If we want to add additional functionalities as described in #3365 we should use frida-compiler so we can separate the different parts of the JS code. For example the value decoders should be separated form the hook-code for better maintainability.

And while the codebase is still small I recommend migrating it to TypeScript.
