Add schema for PCIe aerInfo

A few commits ago, we punted and didn't include a schema for aerinfo.
This commit reenables the json schema, and corrects the config for
the PCIe error fields.

There are certain objects that have zero properties. These are
commented out temporarily to ensure that we don't have empty objects
in the output, which would confuse users.

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.

There are several section arrays in the code that might fail to parse.
When that happens, we'd need to represent the failed section as "null"

Fix bugs in json decode.

Overhaul unit tests to use valijson. Add tests with static examples
to validate against schema. Use and nlohmann for better schema
validation over intrinsic libcper validation.

Fix schemas and add $id properties for oneof[] fields

oneof[] properties are an array of referenced json schemas. In cases
where we need to look through generated logs based on these schemas, it
is much easier to use a hook based on the $id property that uniquely
identifies a nested child property. The $id property allows us to
uniquely identify each data type based on the cper specification.

Fix schemas: Sections and ErrorInformation need a "properties" field
under each oneOf[]. Also add a "type" for cacheError and tlbError to
conform with json schema.

Tested with libcper json validator.
