Add support for testing multi round processors

This CL adds new APIs to run multi-round processors.

Most compilation tests need to run 1 round hence, by default, we invoke
the callback once. If a test wants another round, it needs to register
another callback, which is very similar to an existing api we have in
TestProcessor.nextRunHandler.

Also added utility methods to assert partial diagnostic messages.

Bug: 160322705
Test: MultiRoundProcessingTest, TestRunnerTest
