Solve error prone issues GuardBy, Permission etc.

GuardedBy
* To access mProgress and mClientProgress should hold mProgressLock
* To access mInstallSource, mSessionApplied, mSessionFailed,
  mCommitted should hold mLock
* remove unnecessary @GuardBy for assertNotChildLocked and change
  function name to assertNotChild.
* Doesn't hold two locks as possible.
  as TODO(b/197071589)

  mPm.mInstallerLock

UnusedNestedClass

AndroidFrameworkEfficientCollections
* change List<Integer> to IntArray

AndroidFrameworkEfficientStrings
