Avoid path encoding difference (for example, real_path vs. path from symlink) by eliminating the path from cache key. Cache key is now encoded with the index of the input file from all the input files from the command-line, reguardless if those inputs will produce output or not. This is to ensure stable ordering even the batching is different. Add a new cache computation API that is preferred for using input index directly. Old API for cache key is deprecated but still updated to fallback to real_path comparsion if needed. As a result of swift scan API change, rename the feature in JSON file to avoid version confusion between swift-driver and libSwiftScan. rdar://119387650
