Pull Request Overview

This PR introduces a custom Nx plugin (nx-infra-plugin) to optimize and modernize the build system for the DevExtreme React wrapper package. The changes replace the existing Gulp-based build infrastructure with Nx executors, providing better caching, task orchestration, and maintainability.

Key Changes:

• Created a new nx-infra-plugin package with 8 custom Nx executors for common build tasks
• Migrated devextreme-react build pipeline from Gulp to Nx executors
• Removed Gulp dependencies and replaced with TypeScript-based build tooling

Running pnpm run build from workspace dir packages/nx-infra-plugin will fail with NX Cannot find project 'nx-infra-plugin'. Because NX project has different name with devextreme-* prefix. Though it works fine from repo root nx run devextreme-infra-plugin:build

[alexslavr]

Have you considered running pnpm run build on postinstall?
