sim: Move checkpoint parameters for ptable into seperate section

In checkpoint output files, the parameters for page table including
size and entries are organized not very clearly. For example:

  [system.cpu.workload]
  ...
  ptable.size=...

  [system.cpu.workload.Entry0]
  vaddr=...
  paddr=...
  flags=...

  [system.cpu.workload.Entry1]
  ...

This commit moves these parameters into a separate section named
'ptable'. For example:

  [system.cpu.workload.ptable]
  size=...

  [system.cpu.workload.ptable.Entry0]
  vaddr=...
  paddr=...
  flags=...

  [system.cpu.workload.ptable.Entry1]
  ...
