The ETW registration handle is defined to be 64-bits on all platforms. The Go type previously used a uintptr which created problems on 32-bit systems. This change adds a new wrapper file which receives a 64-bit handle for the functions defined in it, and correctly passes it to the native ETW functions either as-is (on 64-bit) or as two 32-bit values (on 32-bit). This required a minor change in mksyscall_windows.go, to allow multiple syscalls that map to the same underlying function without causing a duplicate definition error in the generated file.
