The code of `ScanDependencies.cpp` was creating invalid JSON since #66031 because in the case of having `extraPcmArgs` and `swiftOverlayDependencies`, but not `bridgingHeader`, a comma will not be added at the end of `extraPcmArgs`, creating an invalid JSON file. Additionally that same PR added a trailing comma at the end of the `swiftOverlayDependencies`, which valid JSON does not allow, but that bug was removed in #66366. Both problems are, however, present in the 5.9 branch, because #66936 included #66031, but not #66366. Besides fixing the problem in `ScanDependencies.cpp` I modified every test that uses `--scan-dependencies` to pass the produced JSON through Python's `json.tool` in order to validate proper JSON is produced. In most cases I was able to pipe the output of the tool into `FileCheck`, but in some cases the validation is done by itself because the checks depend on the exact format generated by `--scan-dependencies`. In a couple of tests I added a call to `FileCheck` that seemed to be missing. Without these changes, two tests seems to be generating invalid JSON in my machine: - `ScanDependencies/local_cache_consistency.swift` (which outputs `Expecting ',' delimiter: line 525 column 11 (char 22799)`) - `ScanDependencies/placholder_overlay_deps.swift`
