[Launcher] Use a keyboard hook in the runner to invoke the Launcher (#6660)
* Added a keyboard hook to the runner

* Update RootKeyboardHook

* Enable reading the whole JsonObject property

* Renamed RootKeyboardHook to CentralizedKeyboardHook

* Fixed build break, changed callback return type to bool

* Added Hotkey struct which somehow went missing

+ Cherry-pick fixes

* Reorganized the kb hook

* Basic version works

* Various fixes

* Finishing touches

* Fix potential threading issue

* int -> size_t

* Add default initializers to the Hotkey struct

* Added a suggested comment

* Unified a constant

* Use C# classes instead of native calls for sync

* Added a claryfing comment

* Use std::move

* Renamed a method

* Possible fix for compilation errors

* Fix a regression
