    frameworks: Exempt location packages from location indicators

    * Otherwise it gets pretty spammy

    config_locationProviderPackageNames:
    * Pretty obvious, location providers, e.g. GMS

    config_locationExtraPackageNames:
    * Pixel 6 IMS package
    * https://cs.android.com/android/_/android/platform/frameworks/base/+/ffb94e69c3fc308d6d4164e2309f74442282fc84
    * This grants location permissions, however we're excluding these apps from
      location indicators - they already have location permissions!
    * https://cs.android.com/search?q=config_locationExtraPackageNames&sq=
    * It isn't used for much else, so it's fine to re-use it for this

    TODO: Figure something out for user-installed UnifiedNlp plugins

    Test:
    1. Open app with location access such as OrganicMaps, verify apps shown as using location
    2. No more regular in background location indicators from UnifiedNlp, or Nearby

    PermissionManager: fix NPE in getIndicatorExemptedPackages

    sLocationProviderPkgNames and sLocationExtraPkgNames can be null
    because they're static.
    Also rename them from member to static variable to follow code style.
