The @nativescript/schematics package uses TypeScript utility functions from @schematics/angular. The utility functions return ASTs generated from the source code. After that these ASTs are used by other functions in @nativescript/schematics.
@nativescript/schematics depends on the version of TypeScript used in the project, whereas @schematics/angular embeds its own version of typescript. If the versions of the two TypeScript packages don't match, we end up comparing ASTs generated from different TS versions which usually results in an error. Currently, we rely on the assumption that the project will have matching versions of @schematics/angular and TypeScript.

With this PR, the code using utilities from @schematics/angular now imports typescript from @schematics/angular guaranteeing the same instance of the TypeScript library will be used.

Looks great! Should we also remove the devDependency to TypeScript?

Tried removing the typescript devDependency, but there are a couple of packages (@phenomnomnominal/tsquery, tslint) that require typescript. Removing the dep will break the tests (also npm run build uses tsc).
