### Description of Change

<!-- Enter description of the fix in this section -->
This pull request introduces a new Material3-based time picker for
Android and updates the handler registration and platform-specific
extensions to support it. The main goal is to enable the use of
`TimePickerHandler2` and `MauiMaterialTimePicker` when Material3 is
enabled, while maintaining compatibility with the existing time picker
otherwise.

### Material3 Time Picker Integration

* Added new `TimePickerHandler2` class for Android, implementing a
Material3-style time picker dialog, with custom mapping and event
handling for properties such as time, format, background, and open/close
state.
(`src/Core/src/Handlers/TimePicker/TimePickerHandler2.Android.cs`)
* Introduced `MauiMaterialTimePicker` control for Android, which wraps
the Material3 time picker UI and exposes methods for showing/hiding the
picker and updating its appearance.
(`src/Core/src/Platform/Android/MauiMaterialTimePicker.cs`)

### Handler Registration Updates

* Modified `AddControlsHandlers` method to register `TimePickerHandler2`
for Android when Material3 is enabled, and fall back to the original
handler otherwise.
(`src/Controls/src/Core/Hosting/AppHostBuilderExtensions.cs`)

### Platform Extension Methods

* Added extension methods for updating format, time, and text color for
`MauiMaterialTimePicker`, mirroring existing methods for the legacy time
picker, and ensuring correct formatting and appearance.
(`src/Core/src/Platform/Android/TimePickerExtensions.cs`)
