Add wayvnc option for sway

This change allows you to start wayvnc anytime your sway session starts.
For hosts where you want to enable this, you'll need to generate the
certificate and keys, see:

https://github.com/any1/wayvnc#encryption--authentication

You can then add these to your secrets via agenix, and load them as
`vnc-key.pem` and `vnc-cert.pem` into `/run/secrets`.

Enable the wayvnc server via the option `pub-solar.sway.vnc.enable`.

At the time of writing, `tigervnc` appears to be a good vnc client to
use.
