feat: Handling regular signals sent to cargo-shuttle on Windows

[Shubham8287]

Description of change

Gracefully handling windows signal to interrupt local run for #872.
/claim #872

How has this been tested? (if applicable)

Tested by running on windows, with Ctrl+C

[Shubham8287]

Right now Implemented handler for Ctrl+C only, it can be extended to other ones. Would love to get some input on which one to add from https://docs.rs/tokio/latest/tokio/signal/windows/index.html.
Also, Signal handler looks is mostly repeated for Unix and windows and between different handlers. Will try to have signal handling as wrapper or something.

I think we need to handle all of them: https://learn.microsoft.com/en-us/windows/console/setconsolectrlhandler#remarks. A default handler for all these signals calls ExitProcess.

Added all the handlers, please review

Seems like tests are failing because of cargo fmt. Can you fix it?

[Shubham8287]

@iulianbarbu passed all checks now.

Thanks @Shubham8287 ! We just need to do some manual testing on a windows machine. We'll follow up after.
