ContextMenuStrip show on wrong monitor about winforms HOT 6 OPEN

@elachlan Here are the test results:

1. This is not a regression issue, it can be reproduced in .NET framework and .NET 6.0 - 9.0.
2. The ContextMenu control does not reproduce the issue.
3. This issue only reproduces when the DPI of the primary screen is less than or equal to the DPI of the secondary screen. The issue does not reproduce when the primary screen DPI is greater than the secondary screen DPI.
4. Using PerMonitorV2 mode does not solve the problem.

Seems to be a known problem for over 9 years: https://stackoverflow.com/questions/26587843/prevent-toolstripmenuitems-from-jumping-to-second-screen/78399012#78399012
I wish you did not remove ContextMenu when the alternative is given so little TLC.

@Olina-Zhang can your team please test this?

@osexpert are both the monitors at normal DPI?

Fantastic analysis! Thanks!

This is not a regression, and it doesn't meet the bar for the team to address in .NET 9 given current priorities. We, of course, wouldn't say no to a community contribution that addresses the issue!
