Merge CSV files generated by UnsupportedAppUsageProcessor.

Flow:
1. Annotation processor generates a CSV file per class as a CLASS_OUTPUT resource.
2. hiddenapi.go extracts individual .csv files and merges them into an index.csv file per module.
3. hiddenapi_singleton.go merges individual index.csv files into a combined .csv file.

In a follow up hiddenapi-index.csv would replace unsupportedappusage_index.csv
