Document Material 3 Android control visuals and platform notes

[SyedAbdulAzeemSF4852]

This pull request updates the Material 3 documentation for .NET MAUI, focusing on Android control rendering when UseMaterial3 is enabled. It adds Material 2 vs Material 3 visual comparisons for supported controls, clarifies Android-only Material 3 behavior, and includes links to the underlying Android components.

Documentation improvements for Material 3 in .NET MAUI:

General updates and clarifications:

• Clarified that Material 3 styling only applies on Android when UseMaterial3 is set to true, and that other platforms are unaffected.
• Updated the page date for accuracy.

Control-specific Material 3 documentation and visuals:

• Added detailed sections for each supported control (Entry, Editor, SearchBar, RadioButton, ProgressBar, Slider, Picker, TimePicker, DatePicker), describing their new Material 3 appearance, with side-by-side screenshot comparisons to Material 2, and links to the underlying Android components.
• For DatePicker, documented the new Material 3 full-screen calendar overlay, immutable calendar constraints, and added an important note about MinimumDate and MaximumDate behavior.
