Add support for compilation on x64 toolchain (x86 cl.exe was running out of heap space in vm.cpp)
Also took the opportunity to change compile optimisation from /Ox to /O2, as /O2 provides better optimisation than does /Ox
Also, we shouldn't be explicitely setting compiler tool defines (__cpp_lib_bitops), so remove that from types.h
libcurl and wolfssl were moved to rpcs3 source control to make buildsystem changes easier.
common_default.props and common_default_macros.props included to project files.
Int and Out Dirs changed to default:
<OutDir>$(SolutionDir)lib\$(Configuration)-$(Platform)\</OutDir> <IntDir>$(SolutionDir)tmp\$(ProjectName)-$(Configuration)-$(Platform)\</IntDir>
