* Removed dprintf from perf library since it is only ever used with fd=1 (STDOUT) so moved to PX4_INFO_RAW instead. This helps with some platforms (e.g. Qurt) which have some Posix support but not full Posix support.
Add interface functions for fetching latency buckets and counters and use
those in perf_counter.cpp. This cleans up the usage of perf counters, when variables defined in hrt_drv are not referenced directly from perf.
This also enables implementing kernel-userspace interface for those for
nuttx protected/kernel build.

- gyro filtering (low-pass and notch) only performed on primary gyro in `sensors/vehicle_angular_velocity` instead of every gyro in `PX4Gyroscope`
- sample rate is calculated from actual updates (the fixed value was slightly wrong in many cases, and very wrong in a few)
- In the FIFO case the array is now averaged and published in `sensor_gyro` for filtering downstream. I'll update this in the future to use the full FIFO array (if available), but right now it should be fine.
