Copy arm64 files for AnyCpu builds

[M4ttsson]

Addition to PR: #5267
Fixes: #4155

Summary:

• Adds arm64 AnyCPU build targets to the NuGet/CefSharp.Common.targets‎ using same layout as for x86 & x64 builds.

Changes:

• Adds CefSharpTargetDirAnyCpuArm64, resolving to arm64\.
• In the CefSharpBuildAction=None AnyCPU path, adds ARM64 copies for:
  • @(CefRedistArm64) — CEF redistribution/native resources
  • @(CefSharpCommonBinariesArm64) — CefSharp.Core.Runtime.dll, browser subprocess files, etc.
  • @(CefSharpCommonManagedDll) — CefSharp.dll, required by the architecture-specific browser subprocess folder
• Adds the same three ARM64 copy rules to the CefSharpBuildAction=Content AnyCPU path.

How Has This Been Tested?

1. Built the CefSharp NuGet packages locally from the netarm64 branch including my changes
2. Configured a .NET Framework 4.8.1 WPF test application to restore CefSharp.Wpf 150.0.110 from that local package feed.
3. Built the test application as AnyCPU, project file included the following.
   <CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport> <CefSharpPlatformTargetOverride>AnyCPU</CefSharpPlatformTargetOverride> <PreferNativeArm64>true</PreferNativeArm64
4. Verified the AnyCPU build output contains all three runtime folders
5. Deployed the AnyCPU output to a native Windows ARM64 VM. The application startup log reported:
   Process architecture: Arm64 Expected runtime: ...\arm64\CefSharp.Core.Runtime.dll Expected CEF runtime: ...\arm64\libcef.dll

I also validated these changes the same way in our product’s cefsharp-browser application: it builds as AnyCPU with the ARM64 CefSharp runtime included and prefers native ARM64 execution on supported Windows devices.

📝 Walkthrough

Walkthrough

The MSBuild targets now define an AnyCPU ARM64 output directory. The None and Content build-action branches copy ARM64 redistribution files, binaries, and managed assemblies into that directory.

Changes

AnyCPU ARM64 packaging

Layer / File(s)	Summary
Define the ARM64 target path NuGet/CefSharp.Common.targets	Adds CefSharpTargetDirAnyCpuArm64, which resolves to the arm64\ subfolder.
Copy ARM64 build outputs NuGet/CefSharp.Common.targets	Copies ARM64 redistribution files, binaries, and managed assemblies for None and Content build actions. Content items retain PreserveNewest and IncludeInVsix settings.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 081c4

The change adds ARM64 runtime files to AnyCPU build outputs; no actionable merge-blocking risk remains beyond normal checks and review.
