* Make tokio::signal::windows::ctrl_c() public. * Stop referring to private tokio::signal::windows::Event in module documentation.

Motivation
When continuously handling Ctrl+C using
tokio::signal::ctrl_c()in a loop, the handler gets registered and deregistered on each iteration. It is useful to instead have an infinite stream of events. This is already possible with signals on Unix andtokio::signal::windows::ctrl_break()on Windows, buttokio::signal::windows::ctrl_c()is currently private.Solution
ctrl_c()public, analogous to the already publicctrl_break().tokio::signal::windows::Eventin the module documentation. ExposingEventwould be an alternative solution here, but the chosen approach seems more consistent with the existing API.
