add explicit @build actions for jdk.test.lib classes in all :tier[1-3] tests

not having explicit @build action might lead to sporadic test failures, therefore all tests directly or indirectly depend on test library classes have to have corresponding explicit build actions.

per Jon Gibbons suggestion[1], all such tests can be found by analyzing classes directory of tests. jdeps tool can be used to get the list of classes required for a specific test.

You might also be able to do run groups of tests (such as all tests that use a given library) and then look for duplicate classes in the compiled classes directory. Such classes will generally be an indication of implicit compilation.
