Use FileTypePolicies as authoritative source for is_archive and is_supported download classifications.

  * Replace all usage of download_protection_util.cc functions except for
    GetDownloadType().
  * Enable it for Android since it will be used for chrome-controlled
    downloads in the future.
  * Make FileTypePolicies thread safe via locking. It's created
    and updated from several threads (between the ZipAnalyzer sandbox,
    SafeBrowsingService, and unit/browser tests). It'll only be accessed
    during downloads and incident reports, and will be updated less than
    once per few hours.

Coming in following CL:
  * Replace all usage of download_extensions.h and FileDangerLevel
