switch to xmake for package management (#611)
This change removes our dependency on vcpkg for package management, in favour of bringing some code in-tree in the `thirdparty` folder as well as using the xmake build-in package management feature. For the latter, all the package definitions are maintained in the zen repo itself, in the `repo` folder. It should now also be easier to build the project as it will no longer depend on having the right version of vcpkg installed, which has been a common problem for new people coming in to the codebase. Now you should only need xmake to build. * Bumps xmake requirement on github runners to 2.9.9 to resolve an issue where xmake on Windows invokes cmake with `v144` toolchain which does not exist * BLAKE3 is now in-tree at `thirdparty/blake3` * cpr is now in-tree at `thirdparty/cpr` * cxxopts is now in-tree at `thirdparty/cxxopts` * fmt is now in-tree at `thirdparty/fmt` * robin-map is now in-tree at `thirdparty/robin-map` * ryml is now in-tree at `thirdparty/ryml` * sol2 is now in-tree at `thirdparty/sol2` * spdlog is now in-tree at `thirdparty/spdlog` * utfcpp is now in-tree at `thirdparty/utfcpp` * xmake package repo definitions is in `repo` * implemented support for sanitizers. ASAN is supported on windows, TSAN, UBSAN, MSAN etc are supported on Linux/MacOS though I have not yet tested it extensively on MacOS * the zencore encryption implementation also now supports using mbedTLS which is used on MacOS, though for now we still use openssl on Linux * crashpad * bumps libcurl to 8.11.0 (from 8.8.0) which should address a rare build upload bug
