Description

This second part of UI Changes and Runtime Improvements PR is focused on moving some custom UI element builder using UIElementExtensions with builder methods to assign the element's properties (for example: Margin, Padding, Columns and Row for Panels like Grid and StackPanel, etc.)

Method Usage Example for UIElementExtensions

Case example

Creating a Grid with 2x2 panel and addin TextBlocks inside it and modify its text

using CollapseLauncher.Extension;

Grid aGrid = UIElementExtensions.CreateGrid()
    .WithColumns(new(1, GridUnitType.Star), new(1, GridUnitType.Star))
    .WithRows(new(1, GridUnitType.Star), new(1, GridUnitType.Star))
    .WithCornerRadius(8d)
    .WithWidthAndHeight(256d);

TextBlock aTextBlock = aGrid.AddElementToGridRowColumn(new TextBlock(), 0, 0);
TextBlock bTextBlock = aGrid.AddElementToGridRowColumn(new TextBlock(), 0, 1);
TextBlock cTextBlock = aGrid.AddElementToGridRowColumn(new TextBlock().WithHorizontalAlignment(HorizontalAlignment.Center), 1, 0, 0, 2);

aTextBlock.Text = "Test A";
bTextBlock.Text = "Test B";
cTextBlock.Text = "Test C";

This PR also brings a new BackgroundMediaUtility to handle the background image/video routine.
Wait, I said "video" there? YES, I also added a support for Video Background. This is a long-waited feature that we have struggled to implement but finally, we are managed to implement this feature thanks to the new BackgroundMediaUtility and its interface to make the implementation easier and more unified.
