Check if TS Generic types should be used

[patric-eberle]

Some components allow to process unknown data (e.g. e-table and e-select). Currently, the expected type is linked to a static interface. It would make more sense to have a Generic here, that allows to specify the data type from outside of the component so that, when the data is emitted back up by event or slot, it's type matches the original one.
