Showcase, Table: Use TableLazyLoadEvent instead of LazyLoadEvent

[can-oezkan]

Describe the bug

The correct type for the onLazyLoad() event is TableLazyLoadEvent.

Showcase still uses LazyLoadEvent which throws a compile error when strictTemplates is enabled in tsconfig.json.

It looks like LazyLoadEvent is never really used anymore and should be removed. I have not removed it in my PR as this would be a breaking change.
