[Feature]: Expose RasterizationScale, ShouldDetectMonitorScaleChanges and RasterizationScaleChanged of CoreWebView2Controller in WebView2 class

[aulati]

Describe the feature/enhancement you need

I need to disable the windows text size scaling while keep the windows dpi scaling.
After some digging I found this: #3699
However I cannot access CoreWebView2Controller in Microsoft.Web.WebView2.WinForms.WebView2, as it's a private field, ShouldDetectMonitorScaleChanges and RasterizationScaleChanged are not exposed in WebView2.

The scenario/use case where you would use this feature

I want to set ShouldDetectMonitorScaleChanges to false, then set the RasterizationScale to the value of DeviceDpi / 96, this would avoid the influence of windows text size scaling.

How important is this request to you?

Impactful. My app's user experience would be significantly compromised without it.

Suggested implementation

Expose those properties/events in Microsoft.Web.WebView2.WinForms.WebView2, or even better, _coreWebView2Controller field.

What does your app do? Is there a pending deadline for this request?

Our app use webview2 and blazor to render WinForms controls on a browser, it's now generally available internally.
