Memory Leak in ListView Control for .NET MAUI

[RiyashameedM]

Description

I've encountered a memory leak issue while working with the ListView control in .NET MAUI. To demonstrate the problem, I've created a video recording which shows the memory usage when navigating away from a page containing the ListView.

Even after navigating away from the ListView page, instances of MyModel continue to exist in memory. I've verified this using profiling tools, which show that they are not being garbage collected as expected.

Steps to Reproduce

1.Run the sample .
2.tap on Navigate Button.
3.And navigate back to the previous.
4.Check the reviewInfo model class using profiler

Please note that the ListView will be deprecated for .NET 10, so we're probably not going to prioritize work on this.
