Adrián Larumbe 434e5ca5b5 drm/panthor: Expose size of driver internal BO's over fdinfo
This will display the sizes of kenrel BO's bound to an open file, which are
otherwise not exposed to UM through a handle.

The sizes recorded are as follows:
 - Per group: suspend buffer, protm-suspend buffer, syncobjcs
 - Per queue: ringbuffer, profiling slots, firmware interface
 - For all heaps in all heap pools across all VM's bound to an open file,
 record size of all heap chuks, and for each pool the gpu_context BO too.

This does not record the size of FW regions, as these aren't bound to a
specific open file and remain active through the whole life of the driver.
