feat: ES modules (ESM) support with conditional esm or commonjs consumption + better error handling

[NathanWalker]

• Conditionally detects .mjs (esm) or .js bundled code
• Loads and executes ES modules
• When module or javascript errors occur, they are caught and proper file/line numbers are printed for better diagnosing

Backwards compatible.

New nativescript.config options

1. logScriptLoading: true: Used to enable verbose terminal output on module resolution.
2. showErrorDisplay: true: Used to display an error screen on the device when errors are encountered. Off by default. Some may prefer to see in terminal only as some will still allow app to continue fine. Other teams may want priority put on all errors that occur so rendering an error screen the moment they happen forces developer to handle them.

Pull Request Overview

This PR adds ES modules (ESM) support with conditional handling of .mjs vs .js bundled code, implements dynamic import() functionality, and enhances error handling in debug mode to prevent app crashes while providing detailed diagnostics through an optional on-device error display.

Key Changes:

• ES module loading with .mjs file detection, module resolution callbacks, and import.meta support
• Enhanced error handling in debug mode that logs detailed stack traces without crashing the app
• Optional on-device error display modal (enabled via showErrorDisplay config option)
