settings: Clean schemas and types used for group settings.

Removed "type"/"Type" from schema and type names used
for group settings because we want to use "type"/"Type"
only for "type of a type" cases.

So, this commit renames-
- anonymous_group_type => anonymous_group_schema
- group_setting_type_schema => group_setting_value_schema
- GroupSettingType => GroupSettingValue

We also had duplicate definitions for GroupSettingType, in
state_data.ts and in settings_components.ts. So, removed it
from settings_components.ts.
