Mark DXGI_SWAP_CHAIN_DESC1::Flags as DXGI_SWAP_CHAIN_FLAG type

[MarijnS95]

This is currently a UINT followed by a comment stating the actual enumeration type that contains the possible flag bits.

[mikebattista]

The types don't match here. You should use the [AssociatedEnum] pattern instead. See #1572.

EMITWINMD : error : Failed to emit DXGI_SWAP_CHAIN_DESC1 in C:\win32metadata\generation\WinSDK\obj\generated\obj\crossarch\common\Dxgi.modified.cs: DXGI_SWAP_CHAIN_DESC1.Flags was remapped to enum Windows.Win32.Graphics.Dxgi.DXGI_SWAP_CHAIN_FLAG (type int, size 4) 
 but the original field was of type UINT (size 4). Either don't use an enum or make sure the enum is of the same size and sign. [C:\win32metadata\generation\WinSDK\Windows.Win32.proj]

Thanks for suggesting that @mikebattista - it looks like the change only landed 3 days ago while this PR is based on commits from ± a week ago because I got many errors when making this change on main with .\DoAll.ps1, perhaps I have to run it with -Clean after any big pull?

At least this got me the right value in ILSpy without errors there, but will try again after rebasing on main!

Yes a clean build would be a good idea if you're having issues. Also make sure you update the baseline per the instructions at the end of the build.

👍 I'll give it a try the next time I boot into Windows...

(Changes pushed here are per request above, but not build-tested locally)

@mikebattista looks like it is working as expected:

Testing .winmd succeeded
*** Comparing .winmd to last release
Unknown differences found:
Windows.Win32.Graphics.Dxgi.DXGI_SWAP_CHAIN_DESC1.Flags :  => [AssociatedEnum(DXGI_SWAP_CHAIN_FLAG)]

     | If all the differences are expected, please update the expected differences list: .\scripts\UpdateChangesSinceLastRelease.ps1 '<add a reason here>'

And according to IlSpy:

public struct DXGI_SWAP_CHAIN_DESC1
{
	// ...

	[AssociatedEnum("DXGI_SWAP_CHAIN_FLAG")]
	public uint Flags;
}

Thanks!
