to make sure that @kubaflo is added as a co-author

This pull request introduces several updates to the `ScrollView` and its
related components to improve layout handling, measurement logic, and
platform-specific implementation for Android. The changes focus on
simplifying code, enhancing functionality, and addressing edge cases in
layout and measurement.

### Enhancements to measurement and layout logic:

- **Refactored `ICrossPlatformLayout.CrossPlatformMeasure` and
`CrossPlatformArrange`:** Improved measurement logic by introducing
explicit constraints based on scroll orientation and utilizing the new
`MeasureContent` method for more accurate content measurement. Added
null checks and default values to prevent errors during layout
operations.

- **Introduced `MeasureContent` method in `LayoutExtensions`:** Added a
new internal method to handle content measurement with support for
explicit dimensions and padding adjustments, improving modularity and
reusability.
(`[src/Core/src/Layouts/LayoutExtensions.csR170-R200](diffhunk://#diff-923a4005b8fd76c6fe5a26814219f9002063666b6d6a49b6b1e19aea086628f4R170-R200)`)

### Platform-specific updates for Android:

- **Updated `MauiHorizontalScrollView` initialization:** Enabled the
`FillViewport` property to ensure the scroll view fills its viewport,
enhancing usability for horizontal scrolling.
(`[src/Core/src/Platform/Android/MauiScrollView.csL100-R104](diffhunk://#diff-546ef8b25e238ce6a1820c920cb327471d6481eefc486eae39b3e5a31b45d907L100-R104)`)
- **Removed unused `CrossPlatformArrange` logic:** Simplified the layout
handling in `MauiScrollView` by removing the `CrossPlatformArrange`
property and related code, which was no longer required.
(`[[1]](diffhunk://#diff-546ef8b25e238ce6a1820c920cb327471d6481eefc486eae39b3e5a31b45d907L232-L240)`,

### Code cleanup and refactoring:

- **Improved readability in `ScrollView` and
`ScrollViewHandler.Android`:** Adjusted formatting and removed redundant
code to enhance clarity and maintainability.
