Add test for tooling invocations set up by CMake API

The purpose of the added test is to verify the way CMake sets up things
like import paths for tooling, in particular qmllint and qmlcachegen.
The test also ensures the application can actually run, which confirms
it can also load the QML module associated with the executable as well
as separate QML modules that have dependencies between them.
