Adjust policy for memory display on APUs (#1967)

* Read the ids_flags when fetching GPU info

The ids_flags contains the flags that can help identify if a GPU
is a dGPU or an APU.

* Show correct memory pool for APUs

The kernel policy for APUs will be to choose the bigger pool of
memory (GTT or VRAM) for KFD work.  Adjust the policy for the monitor
and default commands to show the right memory pool when using an APU.
