DataTable: @state-save emits only if state-key specified

[wouldRewind]

Describe the bug

DataTable @state-save emits only if state-key provided. I think it is a bug or flaw, because in case I want to sync table state with my backend service, I have to find some workaround about this (because I don`t want to use any type of storage - neither "local" nor the "session").

For example: we have prop "v-model:filters", but there is no prop "v-model:columnsWidth" or "v-model:columnsOrders", but I need them. So, that would be very convenient if @state-save emits event, even when state-key prop is not specified.
