RadioButton and CheckBox titles do not resize properly

[rdurfee]

Describe the bug
RadioButton and CheckBox use StackLayout as the base for their controls.

In .NET MAUI, StackLayout no longer constrains to the size of its container. It is recommended to use Grid instead of StackLayout. This will eliminate the issues with the label not reacting to sizing and orientation changes, and it will also fix the issues with LineBreakMode with WordWrap and TailTruncation.

To Reproduce
Steps to reproduce the behavior:

• Launch the Sandbox MAUI app in Windows
• Open the Checkbox page
• Resize the Window smaller and note that the checkbox titles shrink in width
• Resize the Window bigger and note that the checkbox titles do not expand
• On a Surface tablet, changing the orientation from landscape to portrait, the labels will shrink
• Change the orientation back to landscape, and the labels do not expand
• Change the orientation back to portrait again and the labels shrink even further in width
• The same behavior happens on iPad or iPhone when changing the screen orientation

Expected behavior
When the size of the window changes, or the orientation changes, the radio/checkbox text should adjust accordingly. Setting LineBreakMode to TailTrunction should work properly.
