Platform: add DirectX.Direct2D module to WinSDK

[0xpablo]

Adding Direct2D to WinSDK. I tested the change locally and was able to use Direct2D types.

Fixes #57723.

For more context, I was trying to create a shim to expose Direct2D to my Swift package but ran into this assertion (same thing that referenced issue):

  Assertion failed: !D->isUnconditionallyVisible() && "expected a hidden declaration", file C:\Users\swift-ci\jenkins\workspace\swift-6.2-windows-toolchain-arm64\llvm-project\clang\lib\Serialization\ASTWriter.cpp, line 7184
  Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
  Stack dump:
  0.      C:\Program Files (x86)\Windows Kits\10\Include\10.0.26100.0\shared\dxgitype.h:91:3: current parser token 'DXGI_MODE_DESC'

I tried with a variety of toolchains (all with assertions enabled) and they all presented the same issue. I figured that the issue could be related with that type already present in WinSDK, so I decided to try to add the Direct2D module to WinSDK and I got things working.

The ARM64 failure is weird - I think that it is picking up the wrong version of the script somehow 🤔 (CC: @shahmishal)
