drm/panthor: Expose size of driver internal BO's over fdinfo

Browse source

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.
