Port FxCop rule CA2232: MarkWindowsFormsEntryPointsWithStaThread

Title: Mark Windows Forms entry points with STAThread

Description:

STAThreadAttribute indicates that the COM threading model for the application is a single-threaded apartment. This attribute must be present on the entry point of any application that uses Windows Forms; if it is omitted, the Windows components might not work correctly.

Dependency: None

Notes:

@mavasani Is it worth moving/opening a ticket un dotnet/runtime regarding all the CA rules that are still awaiting for port? Some might no longer be relevant or context/recommendation might have changed sightly.

[mavasani]

@Evangelink That seems reasonable to do for all .NET API related rules.

[Evangelink]

Are you considering guidelines related ones (like implement serializable correctly, do this when doing a serialization method....) to also be part of the .NET API?

[mavasani]

Yes

Best to implement this in https://github.com/dotnet/winforms/tree/main/src/System.Windows.Forms.Analyzers

See dotnet/runtime#79602 (comment)

I'll open an issue on dotnet/winforms and close this one.
