Port docs from WinForms

[carlossanlop]

@RussKie @JeremyKuhne This is all I could port from the winforms release/7.0-rc1 branch.

[dotnet-issue-labeler]

I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

Tagging @KlausLoeffelmann since he added the new API to Windows Forms 😉

[RussKie]

Tagging @dreddy-work as he added new API as well

[KlausLoeffelmann]

Looks good to me!

[dreddy-work]

LGTM for Winforms.

[RussKie]

Thank you @carlossanlop and @gewarren for doing this

[carlossanlop]

@cston @dreddy-work @RussKie I'll manually apply the requested changes. But if you have additional feedback, please help @gewarren and I by providing GitHub suggestions with the preferred texts. It's much faster to bulk apply them in a single commit.

System.Windows.Forms.Application.ThreadContext.PreTranslateMessage(Interop.User32.MSG@) doesn't exist, or is internal. Need to remove it.
