`IURL_INVOKECOMMAND_FLAGS` doesn't have `[Flags]` specified.

Actual behavior

I'm pretty sure this should be a bitfield.

namespace Windows.Win32
{
	namespace UI.Shell
	{
		[global::System.CodeDom.Compiler.GeneratedCode("Microsoft.Windows.CsWin32", "0.3.269+368685089b.RR")]
		internal enum IURL_INVOKECOMMAND_FLAGS
		{
			IURL_INVOKECOMMAND_FL_ALLOW_UI = 1,
			IURL_INVOKECOMMAND_FL_USE_DEFAULT_VERB = 2,
			IURL_INVOKECOMMAND_FL_DDEWAIT = 4,
			IURL_INVOKECOMMAND_FL_ASYNCOK = 8,
			IURL_INVOKECOMMAND_FL_LOG_USAGE = 16,
		}
	}
}

Expected behavior

That it be a bitfield.

Repro steps

1. NativeMethods.txt content:

IURL_INVOKECOMMAND_FLAGS

2. NativeMethods.json content (if present): N/A

3. Any of your own code that should be shared? N/A

Context

• CsWin32 version: 0.3.269
• Win32Metadata version (if explicitly set by project): N/A
• Target Framework: net472
• LangVersion (if explicitly set by project): N/A

Start with the generation path for the IURL_INVOKECOMMAND_FLAGS request reproduced through NativeMethods.txt, and compare it with the generated enum shown in the issue. Verify the generated declaration represents the values as a bitfield and add or run the relevant generator test if one exists; done means the repro produces an enum usable for flag combinations.
