Issue Number: #885, #736, #681, #409

What is the new behavior?

Added RegEx Tester to DevToys 2.0.

To achieve it, I needed to fix various bugs to our Monaco wrapper, our Data Grid component and Label component. It includes:

1. Added support of colorful highlighting to Monaco through our API.
2. Remove support of custom selection to Single Line Text Input because there's no API to change the selection in an <input type=text/> outside of SelectAll.
3. Fixed some bugs where DataGrid UI wasn't updating correctly after updating its content.
4. Fixed a bug in Label/TextBlock related to how text wraps.
5. Fixed a bug where Label theme wasn't applied correctly when the component was virtualized into a DataGrid.
6. Fixed a bug where we were triggering Smart Detection for no good reason.
