accel/ivpu: Extend get_param ioctl to identify capabilities

Browse source 
Add DRM_IVPU_PARAM_CAPABILITIES parameters to get_param ioctl to query
driver capabilities. For now use it for identify metric streamer and
new dma memory range features. Currently upstream version of intel_vpu
does not have those, they will be added it the future.
