* fixed UIWebViewImpl-win32 warning C4244 while changing LPWSTR to string
* use direct `socket_native_type`
* directly use HMENU instead of int
* not sure why it wasn't auto converted but msvc spitted warnings
* we're moving it, it doesn't need to be constant, using ntcvt::from_chars
* ignore it to reduce one more warning
* add some missing `noexcept`
* reverted some const removal didn't realize it was used for rvalues
