runtime: abort when receiving a signal on a non-Go thread on Windows

Currently if a signal lands on a non-Go thread that's handled by the Go
handler, Go will emit a message. However, unlike everywhere else in the
runtime, Go will not abort the process after, and the signal handler
will try to continue executing.

This leads to cascading failures and possibly even memory corruption.

For #45638.
