[directx-dxc, directxtk12] update port for July 2022 release and native ARM64 support

[walbourn]

This updates the directx-dxc port for the July 2022 release of the DirectX DXC Compiler on GitHub. This release adds arm64 native support in addition to x64.

This includes an upstream hot-fix to directxtk12

[walbourn]

I don't understand why the arm64-windows failed. The vcpkg.json for directxtk12 lists host: true for directx-dxc, so it should have used the x64-windows version of directx-dxc.

    vcpkg-cmake:x64-windows: SUCCEEDED: 4.693 ms
    vcpkg-cmake-config:x64-windows: SUCCEEDED: 2.794 ms
    directx-headers:arm64-windows: SUCCEEDED: 14.88 ms
    directx-dxc:arm64-windows: SUCCEEDED: 4.415 s
    directx-dxc:x64-windows: SUCCEEDED: 50.44 ms
    directxmath:arm64-windows: SUCCEEDED: 7.456 ms
    directxtk12:arm64-windows: BUILD_FAILED: 2.642 s

Can someone look at the logs more to see why it failed? Locally it builds fine using:

The following packages will be built and installed:
  * directx-dxc[core]:x64-windows -> 2022-07-13
  * directx-headers[core]:arm64-windows -> 1.602.0
  * directxmath[core]:arm64-windows -> 2022-05-18
    directxtk12[core,xaudio2-9]:arm64-windows -> 2022-06-15
  * vcpkg-cmake[core]:x64-windows -> 2022-07-02
  * vcpkg-cmake-config[core]:x64-windows -> 2022-02-06#1

Because directx-dxc has been modified, all its supported triplets will be tested in CI, which is expected. And directx-dxc:x64-windows being installed is proof that host:true is working.
You can understand it this way, there are two ports that need to be tested:

1. directx-dxc (All supported trilpets are installed)
2. directxtk12 (Because it depends on directx-dxc, it will be tested. While installing it, host true worked, so directx-dxc:x64-windows was installed)

Please use following command to reproduce the failure in arm64-windows:
.\vcpkg.exe install directx-dxc:arm64-windows directxtk12:arm64-windows

Failure log:
install-arm64-windows-dbg-err.log
This version of D:\installed\arm64-windows\tools\directx-dxc\dxc.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

This issue should be a bug in directxtk12 https://github.com/microsoft/DirectXTK12/blob/5062aad41e6d701292fa1bad996f6436ee023fd8/CMakeLists.txt#L199

Please add NO_DEFAULT_PATH into the find_program function, I have tested it in my side and .\vcpkg.exe install directx-dxc:arm64-windows directxtk12:arm64-windows run successfully.

Working a fix for upstream.

[Cheney-W]

I saw you have update the upstream, are we currently waiting for the new DirectXTK12 to be released or giving a patch to the DirectXTK12 on vcpkg?

[walbourn]

I am trying to resolve some MinGW issues in directxk12 related to updating the DirectX headers port as well.

[walbourn]

@Cheney-W Have an upstream fix in place, and it builds now.

Once this PR is completed, I'll do a port update for directx-headers and the associated MinGW support changes for directxtk12 and directxtex.
