erp5_officejs_support_request_ui: Dynamically add keys to `count_by_state` dict.

The keys in the `count_by_state` dict in SupportRequest_getSupportRequestStatisticsAsJson.py
was hardcoded in previous version. This commit can add the keys to the dict dynamically according
to the states of Support Request. Thus the code can still work if there has new state added to
Support Request.
