rG0741a2c9caca: [Clang][unittests][NFC] Break up test in Callbacks.cpp
Summary

The Callbacks.cpp test was taking a long time to compile on some build bots
causing timeouts. This patch splits up that test into five separate cpp
files and a header file.

Thank you! LGTM assuming you only moved the tests into separate cpp files (I didn't verify that the text is exactly the same).
