Added "Add record" button in kanban view column headers dropdown (#6649)

Closes #4629 
Refactored `RecordBoardColumnNewOpportunityButton` and
`RecordBoardColumnNewButton` to use the same logic in dropdown.

I kept those hooks inside `record-board-column` where these buttons are.
Let me know if it should be placed somewhere else.

Also Added navigation state preservation when clicked on `edit from
settings`

Thanks :)
