DataGrid - Add `OverflowBehavior` property for a cell/column

[lastunicorn]

As a user of the DataGrid I want to be able to specify how the overflow text to be handled when the width of the cell is not enough for all the data so that I have more control over the way the data is displayed in the cells.

Options for overflow text:

• cut at last character
• cut at last character (with ellipsis)
• cut at last word
• cut at last word (with ellipsis)
• character wrap
• word wrap
