refactor: refactor the Add Input Method page

* Use dcc-widgets and DTK widgets
* Use ListView's rootIndex to implement sub-list and remove complicated logic
* Remove useless refresh logic to optimize the page display speed
* Modify sorting logic, not specialize zh, zh_CN

Fixes linuxdeepin/developer-center#3695
