[examples] Added new gradle tasks for test suites

- generate-/compile-/buildFUMLTestSuite generates/compiles/buildes the whole fUML test suite
- generate-/compile-/buildAllTestSuites generates/compiles/builds all test suites --> currently this only includes fUML test suite since the amount of generated gradle tasks when generating the whole PSCS test suite (ca. 100) causes gradle to crash.

- generate-/compile-/buildPSCSTestSuite tasks are included in the file but commented out (for master branch) until the gradle issue is fixed
