PR Overview
This PR addresses the incomplete label display on macOS and iOS when padding is applied by adjusting the size passed to SizeThatFits.
- Adjust the width and height by subtracting padding values before calculating text size, then add the insets back with AddInsets.
- Add test cases in both TestCases.Shared.Tests and TestCases.HostApp to validate the fix.

Super-nit: After #28040, you can convert this to file-scope namespace by CTRL+. in Visual Studio (I believe it's the same in VS Code).
If it is converted, then new files will use file-scope namespaces more and more as people IMO copy old files to create new code.

Issue Details:
In macOS and iOS, a visibility issue arises when a label fails to display fully when padding is applied to it. The label is completely visible when the padding is removed.
Root Cause
When a direct size value is passed to the SizeThatFits() method, it incorrectly assumes that the label has adequate width to accommodate the text, without accounting for the padding. As a result, the height calculation becomes inaccurate.
Description of Change
To resolve this, the padding value should be subtracted from the width before passing it to SizeThatFits(). This adjustment ensures the width is correctly calculated, leading to an accurate height value. Then added the padding value back in the AddInsets method.
