[DATA GRID] Data grid needs the ability to expand row content into a flyout

[snide]

The truncation rules and custom sizing of data grid is useful for summary level comparisons but often sub-optimal for viewing a single document of data. We should build a simple "expand" button that could show up within the first column of every row and allow the user to view a flyout containing that rows data in a more top-down fashion.

Optionally, an engineer should be able to overwrite this default flyout content and instead populate the flyout with any ReactNode. This should give the flexibility for deep abilities on row based content.

I'm closing this one out. After the solutions presented with control columns in #2846 I think this feature is best addressed downstream, rather than building this into the HoC. I'm going to adjust that demo to better illustrate a way to solve this.
