feat: migrate from Webpack to esbuild for optimized builds

- Updated build process to use esbuild, enhancing performance and reducing bundle size.
- Introduced custom esbuild plugins to replicate Webpack functionality, including removal of duplicate tslib helpers.
- Replaced the previous build script for ES5 with a new optimized version using esbuild.
- Added support for TypeScript in esbuild configuration, ensuring compatibility with existing code.
- Removed Webpack-related dependencies and configurations from package.json and renovate.json.

This transition aims to streamline the build process and improve overall efficiency.
