scripts: Add PowerShell Core tool for cross-platform dependency deployment

[zynfly]

Summary

This PR enables cross-compilation from macOS/Linux hosts to Windows targets by providing PowerShell Core as a vcpkg-managed tool and fixing cross-platform PE dependency analysis.

Problem Description

When cross-compiling to Windows from non-Windows hosts (e.g., ./vcpkg install brotli:x64-mingw-dynamic on macOS), tools are missing required DLL dependencies:

Before this PR:

packages/brotli_x64-mingw-dynamic/tools/brotli/
└── brotli.exe  ← Missing libbrotlidec.dll, libbrotlienc.dll

Root causes:

1. vcpkg_copy_tool_dependencies.cmake required system-installed PowerShell Core, which may not be available
2. applocal.ps1 regex pattern only matched GNU objdump output format (tab-based), not BSD/macOS objdump (space-based)

Solution

1. Add PowerShell Core as vcpkg-managed tool

• New file: scripts/cmake/vcpkg_find_acquire_program(PWSH).cmake
• Downloads PowerShell Core 7.5.4 for 7 platforms:
  • Windows: x86, x64, arm64
  • macOS: x64, arm64
  • Linux: x64, arm64
• Automatically sets execute permissions on Unix platforms

2. Use vcpkg-managed PowerShell

• Modified: scripts/cmake/vcpkg_copy_tool_dependencies.cmake
• Changed from find_program(pwsh) to vcpkg_find_acquire_program(PWSH)
• Eliminates dependency on system-installed PowerShell

3. Fix cross-platform objdump compatibility

• Modified: scripts/buildsystems/msbuild/applocal.ps1
• Updated regex from ^\tDLL Name: to ^[\t ]+DLL Name:
• Supports both GNU objdump (tab) and BSD/macOS objdump (spaces)

Test Plan

Tested on macOS arm64 with MinGW cross-compilation:

./vcpkg install brotli:x64-mingw-dynamic --no-binarycaching

Result: ✅ Success

packages/brotli_x64-mingw-dynamic/tools/brotli/
├── brotli.exe
├── libbrotlidec.dll       ← Direct dependency ✓
├── libbrotlienc.dll       ← Direct dependency ✓
└── libbrotlicommon.dll    ← Recursive dependency ✓

Verified:

• PowerShell Core automatically downloaded and cached
• All vcpkg DLLs correctly identified and copied
• System DLLs correctly skipped
• Recursive dependencies (DLL → DLL) handled correctly

Impact

• ✅ Zero breaking changes: Only affects Windows PE tools in cross-compilation scenarios
• ✅ Backward compatible: Windows native builds continue using existing logic
• ✅ Platform consistency: macOS, Linux, Windows use same tool and workflow
• ✅ No manual setup: Users don't need to install PowerShell Core manually

And add entries to scripts/vcpkg-tools.json for the missing platforms

The # PowerShell tar.gz archives don't have execute permission, so we need to add it part may need to be fixed up in vcpkg fetch itself sadly :/

[zynfly]

I found that other tools, such as coscli, also do not have executable permissions on Linux and macOS. This should be the same as pwsh. How can we handle this more elegantly?

[BillyONeal]

Maybe we should finally just wire up https://github.com/microsoft/vcpkg-tool/blob/main/src/vcpkg/commands.z-applocal.cpp one of these days :/

The only true blocker here is the invalidated authenticode signature.

[BillyONeal]

You have invalidated the signature. This change needs to be made over in https://github.com/microsoft/vcpkg-tool/blob/main/scripts/applocal.ps1

[zynfly]

I have reviewed this C++ code, which is only enabled for WIN32. Should I modify this C++ code to replace the modifications made by pwsh?
