[Feature]: Stream info service

[wrwilliams]

Suggestion Description

Documenting prior discussion with @jrmadsen :

It would be useful to have a callback service providing tools with information about stream creation/deletion/migration if applicable events. Data that we'd like to record in Score-P:

• Which agent is this stream associated with?
• What are its creation parameters, implicit or explicit? (Priority and synchronous/async are the big two.)
• What HSA queue is this stream associated with?
• (Updates if that queue changes)
• Stream deletion

This then lets us maintain a mapping of streams to agents, rather than streams to devices and devices to agents, and gets rid of a bunch of places where we currently need to query the HIP API from tool code.

Additional notes on HIP/SMI calls that we want to be able to avoid in Score-P:

• looking up the device (agent) based on the memory properties of a HIP allocation: can we get malloc/free events with an associated agent?
• looking up the SMI-reported UUID of a device: can this get added to the agent info?
• Agents should have HIP device numbers added; users expect to be able to see device:stream style information describing GPU execution and right now trying to map agent IDs to the HIP layer is messy.

So two services and two extra agent fields would solve a bunch of problems for us.
