…uilds Enables automatic download and configuration of PowerShell Core 7.5.4 when needed for cross-platform builds. This fixes build failures when compiling Windows targets from macOS/Linux, where PowerShell is required for dependency deployment scripts but was previously unavailable. Changes: - Add vcpkg_find_acquire_program(PWSH) for standardized PowerShell acquisition - Update vcpkg_copy_tool_dependencies.cmake to use vcpkg tool infrastructure - Add PowerShell Core 7.5.4 definitions for all platforms in vcpkg-tools.json (Windows x86/x64/arm64, Linux x64/arm64, macOS x64/arm64) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Split from #49890 — this PR extracts the PowerShell Core tool acquisition portion as an independent change.
vcpkg_find_acquire_program(PWSH)module for standardized PowerShell Core acquisition via vcpkg's tool infrastructurefind_program(pwsh)invcpkg_copy_tool_dependencies.cmakewithvcpkg_find_acquire_program(PWSH), eliminating build failures when PowerShell is not pre-installed on the hostvcpkg-tools.jsonfor Windows x86, Linux x64/arm64, and macOS x64/arm64 (Windows x64/arm64 entries already existed)Problem
When cross-compiling Windows targets from macOS or Linux,
vcpkg_copy_tool_dependenciesfails with:PowerShell is required for dependency deployment scripts but the previous code assumed
pwshwas already available on the host system viafind_program().Solution
Use vcpkg's existing tool acquisition infrastructure (
vcpkg_find_acquire_program/z_use_vcpkg_fetch) to automatically download and configure PowerShell Core 7.5.4 when needed. This follows the same pattern used by other vcpkg tools (cmake, ninja, git, etc.) and ensures PowerShell is available on any supported platform without requiring manual installation.Changes
