This commit adds the ability to dump core when sending the `SIGQUIT`
signal on Windows. The change reads in the current registry setting for
local dumps, and attempts to write out to that location before killing
the process. See [collecting-user-mode-dumps] for registry and pathing
details. This behavior mimics that of the dumps created by the typical
Windows Error Reporting mechanism.
