New extra for ACTION_SET_NEW_PASSWORD to specify the min complexity

When an app that has the permission GET_AND_REQUEST_PASSWORD_COMPLEXITY
launches ACTION_SET_NEW_PASSWORD, it can use the DPM PASSWORD_COMPLEXITY_*
constants to specify the complexity it wants in a new extra
EXTRA_PASSWORD_COMPLEXITY.
The screen lock type picker would then filter out the options which
cannot fulfil the min complexity (and DPM restrictions) and will show a
footer with a brief description of the calling app and the requested type.
The same password requirements UI is used in ChooseLockPassword screen
to display the minimum requirements that can fulfil both DPM
restrictions and the min complexity.

The app must have permission GET_AND_REQUEST_PASSWORD_COMPLEXITY
otherwise the extra would be ignored.

ACTION_SET_NEW_PASSWORD is also updated to always display the calling app
name in the screen lock type picker if it is not launched by Settings,
with or without the new extra.
