This is a QOL PR for CsWin32.

• Code Quality: Replace Vanara with CsWin32 #15000

Steps used to test these changes

1. Build Files
2. Open Files

CC: @dongle-the-gadget I used your SG to do this; I'd like to request your review.

1. Is the removal of ThrowOnFailure intended?
2. Can you use the generator on the Storage Provider IID property as well?

1. I wasnt sure if CoCreateInstance fails in any way, these COM interfaces should exist, right?
2. Done.

[dongle-the-gadget]

1. CoCreateInstance could possibly fail, for instance Storage Provider Status would in Windows 10.
2. It seems like the Guid properties in IStorageProviderStatusUI and co. are still manually defined?

1. Coclasses of IFileOpenDialog and IDesktopWallpaper should persist across Windows 10 and 11 versions. But still Im finding a better way to handle HResults in the app (maybe Im gonna return true/false idk) since exception impacts performance iirc.
2. var guid = *IID.IID_IID_IStorageProviderStatusUISourceFactory is fine here?

[dongle-the-gadget]

2 is probably okay, but personally I would use GuidRVAGen on the ref readonly property and then use Unsafe and MemoryMarshal on the pointer one.

Now this is alright?

@yaira2 This is ready.
