CmdPal: Port the devhome perf widgets to cmdpal (#45217)

Pretty direct port of the code, to prove it works.

There's definitely some improvement to be made here, esp WRT to the
network and GPU listing - networks should all just be listed. Or at
least automatically track the active one. And GPU should aggregate a
bunch of stats.

And we can probably add the details to these list items.

But most importantly, _it works_.
