Fix layout rendering, text wrapping, and scrollbar issues

Browse Source 
- LinuxViewRenderer: Remove redundant child rendering that caused "View already has a parent" errors
- SkiaLabel: Consider LineBreakMode.WordWrap for multi-line measurement and rendering
- SkiaScrollView: Update ContentSize in OnDraw with properly constrained measurement
- SkiaShell: Account for padding in MeasureOverride (consistent with ArrangeOverride)
- Version bump to 1.0.0-preview.4
