VaDataTable right click event

[asvae]

Currently for data table component it's pretty hard to implement right click functionality. There is no event on row click. But also, if there is an event - it's tricky for user to figure out how to show dropdown. Right click functionality is a common case for data table.

So we (probably) need:

• an event for right click on row
• an event for right click on cell
• an example with dropdown in docs
• documentation on our approach on this in notion
