fix(@angular/build): check both potential build packages in Angular version check

The compatible Angular version check now supports getting the SemVer range
of a compatible `@angular/compiler-cli` package from both this package
and `@angular-devkit/build-angular` if present. This prevents a potential
build error condition if `@angular-devkit/build-angular` is not present.
