Enable coredumps on Windows

This commit provides two pieces; first, it enables building libuv with
`SIGQUIT` support on Windows (useful for [0]), and second it enables
coredumping when exceptions are hit, after our exception handler has
finished printing out a backtrace.  This is useful for using WER to
create dump files when we segfault, etc...

This commit requires libuv PRs [1] and [2] to properly function.

[0] #45864
[1] JuliaLang/libuv#30
[2] JuliaLang/libuv#31
