Enable RAS manager for fatal and runtime errors

APML RAS Manager Initialization:

- Added initialization for APML RAS Manager.
- Included conditional compilation for APML support.
- Added a placeholder error log for PLDM RAS capabilities, indicating
  that they are yet to be enabled.
- The init function repeatedly attempts to get the BMC RAS OOB
  configuration until successful.
- The function initializes the platform with the block ID's that needs
  to be harvested during a crashdump and sets up a D-Bus match to
  monitor watchdog state changes to monitor BIOS post complete.
- It reads CPU IDs for all CPUs and logs errors on failure.
- The init function also creates separate polling threads for MCA,
  DRAM CECC and PCIE AER error monitoring.
- The function also handles BIOS post-completion by configuring PCIE
  OOB settings and enabling PCIE error thresholds based on watchdog
  timer changes.
- It also clears SbrmiAlertMask register so APML_ALERT_L will be
  asserted during a syncflood in the system.
- The commit has oem_cper.h providing the outline of file format for
  both runtime and crashdump CPER records.
- Added additional json config parameters to enable OOB registers
  during initialization.
- Overall , this commit provides all the necessary preps needed to
  enable the crashdump flow and runtime error monitoring.

Crashdump monitoring:

- This commit introduces the handling of GPIO events for P0 and
  P1 APML alerts
- Binds the P0 alert event handler and P1 alert evernt handler
  to manage these alerts.
- Read RAS status register and check for errors.
- Log and send alerts for various RAS errors including:
  - SYS_MGMT_CTRL_ERR: Trigger cold reset based on policy.
  - RESET_HANG_ERR: Suggest manual immediate reset.
  - FATAL_ERROR: Harvest MCA data and reset based on policy.
  - MCA_ERR_OVERFLOW: Log MCA runtime error counter overflow.
  - DRAM_CECC_ERR_OVERFLOW: Log DRAM CECC runtime error
    counter overflow.
  - PCIE_ERR_OVERFLOW: Log PCIE runtime error counter overflow.

CPER record generation:

- Add functionality to generate Common Platform Error Record (CPER)
  entries when a FATAL_ERROR is detected.
- It also creates CPER record when a runtime MCA , DRAM CECC and
  PCIE AER error is reported via polling or threshold overflow.
- The system stores maximum of 10 CPER records in BMC including
  fatal and runtime errors.
- Create D-Bus object paths for each CPER file in the system,
  allowing for download via redfish.
- Update properties for each CPER object, including Filename,
  Log, and Timestamp.
