mpx - bundling with rolldown

Bundling widgets with rolldown

New build cli that uses rolldown. Should be just drop in replacement for "build" and "start" commands
It should be a drop in replacement. Here is the list of features that I already covered:

• Bundling widget code
• Bundling editorConfig
• Bundling editorPreview
• Images extraction
• CSS extraction
• Typings generator
• MX_PROJECT_PATH support
• MPKOUTPUT support
• minification (alpha)
• full watch mode
• build for native (this needs implementation by mobile team)
• widget deply to target project
• mpk archive

Gotchas

• Have issue with ValueStauts const enum exported from "mendix" package. Can be solved by replacing all uses of enum with appropriate strings (e.g. VaueStauts.Loading => "loading")
  Also, it's good idea to set "isolatedModule: true" in typescript config
• Absolute exports show warnigns (e.g. 'src/utils/dom') and will not be considered as externals.

To test

$ cd packages/mpx
$ pnpm install
$ pnpm pack

And then use tarball to install it to the widget
