Infinite Canvas

### Description

Basically infinite canvas where you can scroll to any side as much as you need and get right coordinates.

### Public API Changes

This is very good example - https://docs.microsoft.com/en-us/windows/communitytoolkit/controls/infinitecanvas

### Intended Use-Case

Something similar to Simulink.

The issue names no files, tests, or entry points. Start by reviewing the linked Windows Community Toolkit InfiniteCanvas example and comparing it with the .NET MAUI UI architecture. Done would require an agreed cross-platform API and implementation scope for an unbounded, coordinate-aware canvas similar to Simulink.
