Subject: Add clang-cl build support

- Add clang-cl warning suppressions in xmake.lua matching Linux/macOS set
- Guard /experimental:c11atomics with {tools="cl"} for MSVC-only
- Fix long long / int64_t redefinition in string.h for clang-cl
- Fix unclosed namespace in callstacktrace.cpp #else branch
- Fix missing override in httpplugin.cpp
- Reorder WorkerPool fields to match designated initializer order
- Use INVALID_SOCKET instead of SOCKET_ERROR for SOCKET comparisons
