[Android] Performance issue with Horizontal ScrollView

[jsuarezruiz]

Description

When using a horizontal ScrollView with a layout, we have an infinite Layout loop dramatically impacting performance.

This is the behavior on Xamarin.Forms:

And this is .NET MAUI:

Steps to Reproduce

1. Sync or download https://github.com/jsuarezruiz/netmaui-chat-app-challenge
2. Launch the App on Android.
3. Try to scroll the top horizontal list (just 10 items in the sample code, 100 in the gif but can see the problem in any case).

similar to #20684 ? Although there are differences in the problem descriptions, I believe these two problems are similar. You can check the CPU differences through commands "adb shell top"
