Can not transpile tns-core-modules with nativescript-dev-webpack

[vchimev]

Describe the bug

The xml-namespace-loader requires the tns-core-modules/xml module.

Respectively, the tns-core-modules package is dependency of nativescript-dev-webpack without referenced in the package.json file.

This restricts transpiling tns-core-modules via nativescript-dev-webpack as the tns-core-modules/xml module is not available at time it is required.

To Reproduce

git clone -b bundle-workflow https://github.com/NativeScript/NativeScript.git
cd NativeScript && npm install
cd ../tns-core-modules && npm install
cd ../tests && npm install
tns run android|ios
