PerMonitorV2: DPI scaling not firing ScaleControl when custom Font is used

• .NET Core Version: 6.0, 7.0/main

• Have you experienced this same bug with .NET Framework?: No (also works in .NET 5)

Problem description:

This is variation of problem reported in #6152 with the twist of setting Font on one of the controls. It is a regression from .NET 5.

Expected behavior:

ScaleControl is called consistently when moving window to display with different DPI.

Minimal repro:

WinFormsApp3.zip

Same repro steps as #6152. The difference is that a custom font is set on one of the UserControls.

So, our Font got disposed from here when the main window was moved to secondary screen: https://github.com/dotnet/winforms/blob/29e805d6d3e60144a31dad96d848cdcfe454e4eb/src/System.Windows.Forms/src/System/Windows/Forms/Control.cs#L12278-L12282
