IA32 EmulatorPkg had many linker warnings because with the current
set of linker flags, the MSVC linker was expecting the __stdcall
calling convention on all entry points. This was an effect of
having /SUBSYSTEM:CONSOLE on all binaries built in EmulatorPkg; this
is only needed on WinHost, as that is what Windows launches. The linker
options are adjusted to only set /SUBSYSTEM:CONSOLE on WinHost.
