Port 6 samples to maven/core-unittests (#4218)
Ported the following samples to unit tests: - SendMessageSample2756 - SetBrowserURLWithJarUrlSample - SetLoopTest2969 - SetPageURLHierarchyTest - ShapeClipTest - ShapeDonutSample Adapted logic to run in headless environment using UITestBase and TestCodenameOneImplementation. Added TestPeerComponent to facilitate BrowserComponent testing. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
