21pages b544a2889b
update vcpkg to 2024.11.16 (#10272)
1. version changes:
* vcpkg: 2024.07.12 -> 2024.11.16
* aom (except linux sciter): 3.9.1 -> 3.11.0
* libvpx: 1.14.1 -> 1.15.0
* libyuv: not update because compiled failed on arm64, and didn't apply
  different version on different archs
* opus: already the latest version
* ffmpeg: 7.0.2 -> 7.1

2. other changes:
* android 5.0 required, otherwise crash when start, because FFmpeg 7.1 link to mediandk directly

3. Tests:
* Except arm, arm64, linux amf, ios, all the other codecs are tested
* Compile on arm32 linux is not tested, ci is failed before vcpkg
  install
* Tested windows FFmpeg qsv, still no memory leak
