[flang] Update output format test to use GTest
Better document each test in output formatting tests. Use GTest primitives and infrastructure in same
spirit as [[ https://reviews.llvm.org/D97403 | D97403 ]]. [[ https://github.com/flang-compiler/f18/issues/995#issuecomment-790737912 | See legacy github issue linked here ]] for additional context. Reorganize long test cases to be more readable.
