GSettingsSchema: add g_settings_schema_list_keys()

Browse Source 
The list of keys in a GSettings object depends entirely on the schema,
so it makes sense to expose this API there.

Move the implementation out of gsettings.c and into gsettingsschema.c,
replacing the earlier with a simple call to the new location.

We don't do the same for children because the children can change.
