fru-device: Add support to dynamically add FRU fields
This patch adds the ability to dynamically add or update FRU fields
at runtime, enhancing system flexibility in managing FRU data.
Previously, field modification was limited to the preassigned space
available in the FRU area. Any attempt to exceed this boundary would
fail:
Example:
```busctl set-property xyz.openbmc_project.FruDevice /xyz/openbmc_project/FruDevice/MDA_WCU_AI xyz.openbmc_project.FruDevice CHASSIS_SERIAL_NUMBER s "1234567890123"
busctl set-property xyz.openbmc_project.FruDevice /xyz/openbmc_project/FruDevice/MDA_WCU_AI xyz.openbmc_project.FruDevice CHASSIS_SERIAL_NUMBER s "12345678901234"
Failed to set property CHASSIS_SERIAL_NUMBER on interface xyz.openbmc_project.FruDevice: Invalid argument
hexdump -C /sys/bus/i2c/drivers/at24/8-0051/eeprom
```
With this patch, the FRU area can extend dynamically. All FRU areas are
repacked, and the FRU common header is updated without errors:
Example:
```
busctl set-property xyz.openbmc_project.FruDevice /xyz/openbmc_project/FruDevice/MDA_WCU_AI xyz.openbmc_project.FruDevice CHASSIS_SERIAL_NUMBER s "1234567890123"
busctl set-property xyz.openbmc_project.FruDevice /xyz/openbmc_project/FruDevice/MDA_WCU_AI xyz.openbmc_project.FruDevice CHASSIS_SERIAL_NUMBER s "12345678901234567890123456789"
```
Also check eeprom so that FRU areas get aligned properly.
Key changes:
- Introduced support through the `UpdateFruField` API.
- Utilizes `disassembleFruData` to parse existing FRU data into editable
fields.
- Applies field changes using `setField`, which handles updates or
additions.
- Reconstructs updated FRU binary data with `assembleFruData` before
committing it back.
TESTED=Build for Tiagopass & test on QEMU using below commands:
busctl call xyz.openbmc_project.FruDevice \
/xyz/openbmc_project/FruDevice/BMC_Storage_Module \
xyz.openbmc_project.FruDevice UpdateFruField ss \
"CHASSIS_INFO_AM10" "1234567890"
Readback:
busctl introspect xyz.openbmc_project.FruDevice \
/xyz/openbmc_project/FruDevice/BMC_Storage_Module
