Allow perfetto to access gpu_frequency tracepoint in user

This will allow Perfetto to capture GPU frequency changes
on the target, which is useful to graphics developers
using Perfetto to profile graphics HW usage.

This change also updates the private prebuilt at version
29.0 to match the update.
