Ensure all passing user tests are called by their appropriate suite

Fixes #10258

Listing all .*Test.java files, comparing with grep result for \w+Test.class in source and eliminating abstract classes + not actual tests gives this:

AbstractSequentialListTest.class - testclass itself not abstract
AtomicReferenceTest.class
BidiFormatterBaseTest.class
EmmaClassLoadingTest.class
HasAlignmentParserTest.class - no GWTTestcase
HorizontalAlignmentConstantParser_Test.class - no GWTTestcase
ImageElementTest.class
LayoutPanelTest.class
NoGenerateJsInteropExportsTest.class (@DoNotRunWith(Platform.Devel))
RPCTypeCheckArraysTest.class - no GWTTestcase
RPCTypeCheckCollectionsTest.class - no GWTTestcase
SafeHtmlBidiFormatterTest.class - no GWTTestcase
SelectionScriptJavaScriptTest.class - no GWTTestcase
StringReaderTest.class
VerticalAlignmentConstantParser_Test.class - no GWTTestcase

PR description specificaly mentions passing tests, I didn't try running any of these. The two test classes with underscore look like old versions of their conventionally named siblings and should be probably deleted.

Please check if some of the classes in my previous comment could/should be enabled too.
