Ensure we're not doing device-info queries for 'alive' devices unless necessary

[TwitchBronBron]

There might be situations where the ssdp 'alive' response shows up and vscode isn't focused. in that case, we really shouldn't be running device-info requests over and over. (think keeping vscode focused over a 3 hour lunch break when someone's constantly power-cycling their roku).

So ensure we store the IP of that device, but don't device-info it until we actually need it (same as all other device types).

Consider what information is shown in the popup, might be an argument for doing the request sometimes (still consider focused/not-focused though)
