Free telemetry from frame data

[planetchili]

Having the telemetry data tied to frames in the IPC shared memory has several drawbacks:

• Redundant telemetry usage when frame rate exceeds telemetry sample rate
• Redundancy when tracking multiple processes
• Redundancy multiplied by number of devices in multi-device scenarios
• Inability to measure telemetry when frame rate is low / non-existent
• Extra work aligning telemetry data that may not be consumed

Storing the telemetry samples in its own structure at a different rate than frame rate solves this. This means when alignment is done (during frame data event capture), it will be done on the middleware side on demand.
