Ensure BMC image is compatible with MB CPLD version

Summary: grandteton versions v2024.11.1 require MB CPLD version `20010` or greater.  Added `checks_and_remediations` step to fail the upgrade if the MB CPLD version is incompatible with the image version.

Test Plan:
Unit tests, push flashy/bmc images to grandteton units e.g:

```
$ scripts/run_flashy_remote.sh --device mtd:flash1 --imagepath /tmp/tmp.H8gzWMVfip/openbmc.image.grandteton\:v2024.11.1/flash-grandteton --host twshared39604-oob.02.nao6.facebook.com --dry-run
```
Run step on a BMC with image version = v2024.11.1 and old MB CPLD (should fail):
```
#  /run/flashy/flashy --install && /run/flashy/checks_and_remediations/grandteton/00_ensure_compatible_mb_cpld_version --imagepath /run/upgrade/image --device mtd:flash1
...
{"message":"S365492: Image version ('grandteton-v2024.11.1') requires MB CPLD version 20010 or greater (current MB CPLD version is 20006)"}
```

Run step on a BMC with image version = v2024.11.1 and new MB CPLD (should succeed):
```
/run/flashy/flashy --install && /run/flashy/checks_and_remediations/grandteton/00_ensure_compatible_mb_cpld_version --imagepath /run/upgrade/image --device mtd:flash1
...
2024/04/09 08:33:48 MB CPLD version 20010 is compatible with image version grandteton-v2024.11.1
```

Run step on a BMC with image version < v2024.11.1 and old MB CPLD (should succeed):
```
#  /run/flashy/flashy --install && /run/flashy/checks_and_remediations/grandteton/00_ensure_compatible_mb_cpld_version --imagepath /run/upgrade/image --device mtd:flash1
...
2024/04/09 08:35:46 MB CPLD version 20006 is compatible with image version grandteton-v2023.39.2
```

Run step on a BMC with image version < v2024.11.1 and new MB CPLD (should succeed):
```
#  /run/flashy/flashy --install && /run/flashy/checks_and_remediations/grandteton/00_ensure_compatible_mb_cpld_version --imagepath /run/upgrade/image --device mtd:flash1
...
2024/04/09 08:40:29 MB CPLD version 20010 is compatible with image version grandteton-v2023.39.2
```
