Transfer to @rust-windowing

[madsmtm]

@msiglreith seems to not have the time to maintain this any more (if I understood correctly?), so we should transfer this to the @rust-windowing organization. This was agreed on at the previous Winit meeting.

Tasks:

• Move repository.
• Transfer crate ownership on crates.io to madsmtm, daxpedda and kchibisov.
• Create a team @rust-windowing/raw-window-metal, and add that as publisher on crates.io.

thanks, transfer should be complete
minor point: some readme links are referring to norse-rs

[madsmtm]

Wonderful, thanks!

(And thanks for your contributions over the years to Winit and the rest of the ecosystem, wish you well in your current/future endeavours, whatever those may be ;) )
