Pull request overview

Migrates key DevExtreme build steps from Gulp scripts to Nx targets/executors (part 1), introducing a reusable “workflows” Nx project and updating CI to use Nx configurations.

Changes:

• Added new custom Nx executors (localization generation, Babel transform, file concatenation) and expanded existing infra executors.
• Reworked devextreme Nx targets to model localization/transpile/bundle/npm steps and wired Gulp tasks to call Nx targets.
• Updated repo build/test entrypoints and CI workflows to run Nx targets/configurations for testing/dev builds.
