Update policy_ui_handler to use new Policy conversions.

GetAllPolicyValuesAsArray is replaced with ArrayPolicyConversions.
Enable policy value conversion.

Use default settings that includes user policies, disable device data,
enable pretty print and convert policy types to string.

GetAllPolicyValuesAsDictionary is replaced with DictionaryPolicyConversions.
All config is set to defaults. Pretty print, policy type conversion and
user policies are enabled. Device data and policy value conversions are
disabled.
