go.sys/windows: use syscall.Errno for windows errors

If we use a local type, it won't compare properly with errors from the rest of the standard library. Errors are the one type from syscall that propagates through the system, so it's important to have only one type for them. mkerrors_windows.sh is gone, so: - rename zerrors_windows.go and delete its DO NOT EDIT mark - delete the contentless zerrors_windows_*.go files LGTM=rsc R=rsc CC=alex.brainman, golang-codereviews https://golang.org/cl/122600043
