Update vcpkg baseline, remove libvpx overlay

Use rapidjson master in discord-rpc

See merge request KartKrew/Kart!2376

The last stable version of rapidjson was in 2016, and it is
unlikely that neither rapidjson nor discord-rpc will receive a
stable release ever again. However, rapidjson has a lot of fixes
merged in their tree, so in order to fix gcc 14 compilation issues,
let's pull in that tree.

The upstream changes for libvpx on Windows were merged and so this
overlay is no longer needed.

Updating the baseline requires everyone to update their vcpkg repo
locally (git pull). It also upgrades all dependencies used.
