Bug: 22718745 Intents to 'draw over other apps' should go direct to the package's

page instead of the top level one

Settings:
Added two activities to handle app-specific Intent when app invoke permission
management UI.

SettingsActivity:
Added two fragment classes to handle app-specific Intent when app invoke permission
management UI.

AndroidManifest.xml:
We handle both Intent to top level settings and app-specific management UI for
app ops protected permissions.

AppStateAppOpsBridge:
Added a new field to PermissionState to keep track of permission declared vs one
that is actually granted during install time.

AppState{Overlay/Usage/WriteSettings}Bridge:
Updated the fields affected by changes in PermissionState.

{DrawOverlay/UsageAccess/WriteSettings}Details:
Disabled the toggling of permission if the app did not declare for the asked
permission.
