use google quiche as library

Reason

The reason is simple: There are always so many projects that are not managered by build.gn.
1 install llvm
Reference:
2 download chromium project
I choose naiveproxy.
3 change some compiling flags in build.sh

  out=out/Release
  flags="
    clang_base_path=\"/usr\"
    clang_use_chrome_plugins=false
    use_custom_libcxx=false
    is_official_build=false
    exclude_unwind_tables=true
    enable_resource_whitelist_generation=false
    is_component_build=true
    target_cpu=\"x64\"
    symbol_level=0"

 After several error, I found the net library is denpended on libstdc++ instead of libc++.
