Get GenericScopedHandle::Set to preserve LastError code
Code like this is elegant and clean and common in Chrome:
event_.Set(CreateEvent(NULL, FALSE, FALSE, wname.c_str()));
if (event_.Get() && GetLastError() != ERROR_ALREADY_EXISTS) {
However it will behave incorrectly if event_.Set() zeroes out the
Windows LastError code, which VC++ 2015 frequently does. This change
avoids that.
