[FIX] Update vcpkg baseline and rsmpeg to fix Windows build

Update vcpkg baseline from Feb 2024 to Dec 2025 to resolve libxml2
hash mismatch. GitLab regenerates archives dynamically, causing
SHA512 verification failures with old baselines.

Update rsmpeg to 0.15.1 with ffmpeg7 support for Windows to match
the ffmpeg 7.1.2 provided by the new vcpkg baseline.
