Add selected property support for ListItem in Blazor code generation

[valeriatoneva]

Now that the List (specifically ListItem) component has a new selected property in App Builder, we need to generate it properly for Blazor as well. Currently, this property is already implemented for Web Components, Angular, and React, but Blazor support is missing.
The feature ensures that the selection of a list item is persisted across pages and within the current view.
Work item reference: AB #38726

Acceptance Criteria:
The selected property is generated for Blazor ListItem components in the same way as for WC, Angular, and React.
Selection state persists across page navigations and within the current view.

Additional Context:
Web Components, Angular, and React already implement this feature.

Feature - IgniteUI/igniteui-webcomponents#1590

The selected property of the list-item is introduced in the following version of Blazor(24.2.111) - https://www.infragistics.com/products/ignite-ui-blazor/blazor/components/general-changelog-dv-blazor?_ga=2.99185622.979049635.1755184552-1568739105.1702626829#242111-april-2025

Please make sure you are testing it with it or later one.
