Fix potential deadlock in getAutofillOptions().

The getAutofillOptions() holds the main service lock, we move disable
autofill information from AutofillManagerService to AutofillOptions
in ag/8684509, it may possible cause circular lock between
AutofillManagerService.

Move the disable information to another class DisabledInfoCache, keyed
by user id. We can use a new lock inside this class to prevent use
main service lock
