Added activity for the ACTION_DIRECTORY_ACCESS_SETTINGS intent.

Applications typically use this action to ask the user to revert the
"Do not ask again" status of directory access requested made by
StorageVolume.createAccessIntent(directory).

Test: adb shell am start -a android.settings.DIRECTORY_ACCESS_SETTINGS
Test: atest CtsAppSecurityHostTestCases:ScopedDirectoryAccessTest#testResetDoNotAskAgain
