[build-tools] label serve-sim metrics artifacts with the device name

[gwdp]

Why

We want to have a device name in the metrics file, since today it's just a hex users can't really make sense if multiple devices are used

How

Reads deviceName from the meta (serve-sim 'now' sends it: expo/serve-sim#37) and uses it for the artifact's display name. No-op until serve-sim ships it so we can roll this out independently

Test Plan

CI passes w/ new unit tests
