runtime: remove unused badsignal2 on windows
This CL removes badsignal2 function, as it is unused on Windows.
badsignal2 was originally intended to abort the process when
an exception was raised on a non-Go thread, following the same approach
as Linux and others.
Since it was added, back on https://golang.org/cl/5797068, it has caused
several issues on Windows, see #8224 and #50877. That's because we can't
know wether the signal is bad or not, as our trap might not be at the
end of the exception handler chain.
To fix those issues, https://golang.org/cl/104200046 and CL 442896
stopped calling badsignal2, and CL 458135 removed one last incorrect
call on amd64 and 386.
