Update docs (tracing-sdk): link system_libs (for different target platforms) and define `_WINSOCKAPI_` , `NOMINMAX` on windows

[blockspacer]

Update docs (tracing-sdk): https://perfetto.dev/docs/instrumentation/tracing-sdk

target_compile_definitions(perfetto PRIVATE 
  NOMINMAX # WINDOWS: to avoid defining min/max macros
  _WINSOCKAPI_ # WINDOWS: to avoid re-definition in WinSock2.h
)

Without NOMINMAX i get error

perfetto.cc(3090,14): error: expected unqualified-id
        std::min(count - written, static_cast<size_t>(UINT32_MAX)));

Without WINSOCKAPI i get error

May also require (not sure):

    _USE_MATH_DEFINES
    _CRT_RAND_S
    _CRT_SECURE_NO_WARNINGS

Windows 10, clang-cl

I suppose that tracing-sdk requires system libs similar to pseudo-code below:

        if self.settings.os == "Windows":
            self.cpp_info.components["libperfetto"].system_libs.append("wsock32")
            self.cpp_info.components["libperfetto"].system_libs.append("ws2_32")
        if self.settings.os in ["Linux", "FreeBSD"]:
            self.cpp_info.components["libperfetto"].system_libs.append("pthread")
            if self._is_clang_x86 or "arm" in str(self.settings.arch):
                self.cpp_info.components["libperfetto"].system_libs.append("atomic")
            if self.settings.os == "Windows":
                if self.options.shared:
                    self.cpp_info.components["libperfetto"].defines = ["PROTOBUF_USE_DLLS"]
            if self.settings.os == "Android":
                self.cpp_info.components["libperfetto"].system_libs.append("log")

I updated our doc to match the example in
