[regression/8.0.0] Binding a Color from a model is broken on Windows

[jeremy-visionaid]

Description

All model bindings appear to break on Windows when attempting to bind a color (e.g. Label.BackgroundColor)

Steps to Reproduce

A repo is available here based on CollectionViewDemos from maui-samples:

https://github.com/molesmoke/MauiTestApp/tree/binding

Expected outcome: The view dispays the model data displayed with a red label background
Actual outcome: The view displays only placeholders for the model data

This appears to work OK on Android at least, so probably a Windows-specific issue

Confirmed that this regressed between 7.0.92...8.0.0-preview.1.7762. Still reproducible on nightly. Because it can't find the binding on the model, I am 90% sure it's a duplicate of #16787.
