Implement support for POZ FFDC with multiple FFDC packets

This commit implements support for POZ FFDC, where multiple FFDC packets
can be returned after executing an SBE chip-op. This differs from the
processor SBE chip-op, which typically returns only a single FFDC packet
upon a chip-op failure.

Key aspects of the implementation:
- Each FFDC packet is associated with a unique SLID id, allowing for the
  identification of separate and unrelated FFDC packets within the
collection.
- Each unique SLID is treated as an independent PEL, ensuring that each
  FFDC packet is logged separately.
- FFDC data may be present even if the chip-op completes successfully.
  In such cases, PELs are logged, but the chip-op is not considered a
  failure.

Tests:
  Testing the proc FFDC to make sure no regression
  Testing POZ FFDC and making sure multiple PELs are logged
  Testing FFDC with chip-op success
