Tests: Remove all file(GLOB) from CMakeLists in Tests
Using a file(GLOB) to find all the test files in a directory is an easy hack to get things started, but has some drawbacks. Namely, if you add a test, it won't be found again without re-running CMake. `ninja` seems to do this automatically, but it would be nice to one day stop seeing it rechecking our globbed directories.
