PCIe CPER Section Enhancement

This commit improves PCIe error reporting capabilities by:
- Adding support for PCIe capability version detection and parsing
- Expanding Advanced Error Reporting information extraction

The changes include:
- New capability_registers structure to decode PCIe capability registers
- Updated PCIe JSON Schema to match
- Support for PCIe 2.0+ extended registers when detected
- Improved error source identification and root error status reporting
- Fix typo for Advanced Error Reporting capabilit[i]es_control
- Updated generate/gen-section-pcie.c and pcie.json example

In the future we could:
- Implement TLP header log parsing with detailed descriptions
- Add support for Flit mode in PCIe 2.0+ devices

Tested:
- test/cper-tests passes
- cper-convert to-json|to-cper on pcie.cper|json in example path
- Tested "cper-convert to-json-section" using an extracted OS GHES PCIE
CPER from error injection and compare against expected values

Note, schema validation is intentionally less restrictive than it could
be for pcie advanced error reporting as it evolves.
