[FIX] Update vcpkg baseline and use forked rsmpeg for FFmpeg 7

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.

Switch to CCExtractor's forked rsmpeg (github.com/CCExtractor/rsmpeg)
which pins rusty_ffmpeg to 0.16.4 for FFmpeg 7.1 compatibility.
This provides consistent FFmpeg 7 support across all platforms.

Changes:
- Update vcpkg baseline in workflow and vcpkg.json
- Use forked rsmpeg from git for all platforms
- Use ffmpeg7_1 feature instead of ffmpeg6/ffmpeg8
- Use link_vcpkg_ffmpeg for Windows
