hariel1985 c9cd87f221 Show RAM and compressed memory per process ...

Adds two columns to the Processes table (and rows to the inspector) next
to Memory, which is the physical footprint:

- RAM: pages currently in physical memory (ri_resident_size, from the
  proc_pid_rusage call that was already being made).
- Compressed: the original size of the process's pages held by the
  compressor, via task_name_for_pid + TASK_VM_INFO. This is also the
  closest per-process swap figure: macOS pages out compressor segments,
  not processes, and those stay counted here. Activity Monitor's
  "Compressed Memory" and top's CMPRS report the same value.

Both need no privileges for the user's own processes; other users' and
system processes report 0, as the Memory column already did. Values match
top/ps within sampling noise; a full refresh of ~650 processes including
the extra call takes ~5 ms.

Memory, RAM and Compressed live in one @TableColumnBuilder property:
Table takes at most 10 columns per block, and inlining them also
exceeded the type checker's time limit.
