accel/ivpu: Add NPU profiling support

Implement time based Metric Streamer profiling UAPI.

This is a generic mechanism allowing user mode tools to sample
NPU metrics. These metrics are defined by the FW and transparent to
the driver.

The user space can check for this feature by checking
DRM_IVPU_CAP_METRIC_STREAMER driver capability.
