move cpr in-tree (#605)

* added cpr 1.10.5 in-tree to allow updates to vcpkg without breaking the build
* added asio 1.29.0 in-tree to remove one more vcpkg dependency
* bumped vcpkg to 2024.06.15 to address failure to build due to use of deprecated binaries in vcpkg (404 error: `https://mirror.msys2.org/mingw/mingw64/mingw-w64-x86_64-pkgconf-1~2.1.0-1-any.pkg.tar.zst` during build)
