Summary:
Running `instruments -s devices` causes the `pkd` process in catalina to spike to ~100% for a few seconds.
Flipper runs this command every 3 seconds to poll for devices.
This switches it to use `idb list-targets` instead which is much more performant.
Currently switched off in the open-source version while we make sure it's working well. If you set the GK value 'flipper_use_idb_to_list_devices' to true, then you'll get the new behaviour.
