Update chrome_cleaner dirs from internal repo: chrome_utils, crash, logging

Get changes from the internal repo since last branch point:
- chrome_utils now uses the sandboxed JsonParser to parse extension install methods
- add JsonParser sandbox to crash client and process information logging
- get internal API keys for official build, dummy API keys for public build
- Add FOUND_IN_PROGRAMFILES trace location
