Pull request overview

This PR reverts the Angular package migration to Nx, moving it back to a Gulp-based build system while keeping React and Vue packages on Nx. The change removes Angular-specific Nx executors and dependencies.

Key changes:

• Migrated devextreme-angular from Nx executors back to Gulp build system
• Removed Angular-specific executors (karma-multi-env, build-angular-library, generate-component-names) from nx-infra-plugin
• Simplified nx-infra-plugin by removing fs-extra, ng-packagr, and karma peer dependencies
• Updated React and Vue package configurations to use simplified Nx targets
