i2cvr: restrict apply time to OnReset

Applying VR firmware updates with Immediate ApplyTime may trigger
power fluctuations in a running system and lead to unstable or
abnormal behavior. To ensure safe updates, the ApplyTime for VR
devices is restricted to OnReset. This guarantees updates occur
only during a system reset, when power rails are stable.

Add i2c voltage regulator updater

- /i2c-vr: Classes following the design in [1]
- /i2c-vr/vr.cpp, vr.hpp: General representation of a voltage regulators
communication interface
- /vr-i2c/xdpe1x2xx: Support for Infineon XDPE1x2xx class of voltage
regulators
- /common/i2c/: Basic I2C communication interface

The configuration of a voltage regulator relies on the EM-Schema in [2]

2: https://gerrit.openbmc.org/c/openbmc/entity-manager/+/77463

Tested on QEMU/Yosemite4:

1. Display the firmware inventory
```
curl --insecure --user root:0penBmc \
https://127.0.0.1:2443/redfish/v1/UpdateService/FirmwareInventory
```

Output:
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/16bae6fd"
},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/DummyDeviceFirmwareName_6637"
},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/Management_Board_cpld"
},
{...}
```

2. Query voltage regulator version

The dummy device sets the default version to 0xBEEF (Decimal: 48879)
```
curl --insecure --user root:0penBmc \
https://127.0.0.1:2443/redfish/v1/UpdateService/FirmwareInventory/
DummyDeviceFirmwareName_4390
```

Output:
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/DummyDeviceFirmwareName_4390",
"@odata.type": "#SoftwareInventory.v1_1_0.SoftwareInventory",
"Description": "Other image",
"Id": "DummyDeviceFirmwareName_4390",
"Name": "Software Inventory",
"Status": {
"Health": "Warning",
"HealthRollup": "OK",
"State": "Disabled"
},
"Updateable": false,
"Version": "48879"
}
```

3. Trigger the update
```
curl -k --insecure --user root:0penBmc \
-H "Content-Type:multipart/form-data" \
-X POST \
-F UpdateParameters="{\"Targets\":[\"/redfish/v1/UpdateService/FirmwareInventory/DummyDeviceFirmwareName_4390\"],\"@Redfish.OperationApplyTime\":\"Immediate\"};type=application/json" \
-F "UpdateFile=@fw_vr_update.bin;type=application/octet-stream" \
https://127.0.0.1:2443/redfish/v1/UpdateService/update
```

4. Task is returned
```
{
"@odata.id": "/redfish/v1/TaskService/Tasks/0",
"@odata.type": "#Task.v1_4_3.Task",
"Id": "0",
"TaskState": "Running",
"TaskStatus": "OK"
}
```
5. Query the task
```
curl --insecure --user root:0penBmc \
https://127.0.0.1:2443/redfish/v1/TaskService/Tasks/0
```

Output:
```
{
"@odata.id": "/redfish/v1/TaskService/Tasks/0",
"@odata.type": "#Task.v1_4_3.Task",
"EndTime": "2025-03-10T13:47:34+00:00",
"HidePayload": false,
"Id": "0",
"Messages": [
{
"@odata.type": "#Message.v1_1_1.Message",
"Message": "The task with Id '0' has started.",
"MessageArgs": [
"0"
],
"MessageId": "TaskEvent.1.0.TaskStarted",
"MessageSeverity": "OK",
"Resolution": "None."
},
{
"@odata.type": "#Message.v1_1_1.Message",
"Message": "The task with Id '0' has completed.",
"MessageArgs": [
"0"
],
"MessageId": "TaskEvent.1.0.TaskCompletedOK",
"MessageSeverity": "OK",
"Resolution": "None."
}
],
"Name": "Task 0",
"Payload": {
"HttpHeaders": [],
"HttpOperation": "POST",
"JsonBody": "null",
"TargetUri": "/redfish/v1/UpdateService/update"
},
"PercentComplete": 0,
"StartTime": "2025-03-10T13:47:34+00:00",
"TaskMonitor": "/redfish/v1/TaskService/TaskMonitors/0",
"TaskState": "Completed",
"TaskStatus": "OK"
}
```

6. Display fw inventory after update
```
curl --insecure --user root:0penBmc \
https://127.0.0.1:2443/redfish/v1/UpdateService/FirmwareInventory
```

Output:
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory",
"@odata.type": "#SoftwareInventoryCollection.SoftwareInventoryCollection",
"Members": [
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/16bae6fd"
},
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/DummyDeviceFirmwareName_282"
},
{...}
}
```

7. Query the new fw version.

The version is 'mycompversion' since that's what has been set in the
pldm fw update package for testing.

```
curl --insecure --user root:0penBmc \
https://127.0.0.1:2443/redfish/v1/UpdateService/FirmwareInventory/
DummyDeviceFirmwareName_282
```

Output:
```
{
"@odata.id": "/redfish/v1/UpdateService/FirmwareInventory/DummyDeviceFirmwareName_282",
"@odata.type": "#SoftwareInventory.v1_1_0.SoftwareInventory",
"Description": "Other image",
"Id": "DummyDeviceFirmwareName_282",
"Name": "Software Inventory",
"Status": {
"Health": "OK",
"HealthRollup": "OK",
"State": "Enabled"
},
"Updateable": false,
"Version": "mycompversion"
}
```

8. Update in progress error

```
curl -k --insecure --user root:0penBmc \
-H "Content-Type:multipart/form-data" \
-X POST \
-F UpdateParameters="{\"Targets\":[\"/redfish/v1/UpdateService/FirmwareInventory/${TARGET}\"],\"@Redfish.OperationApplyTime\":\"Immediate\"};type=application/json" \
-F "UpdateFile=@${FWPATH};type=application/octet-stream" \
https://127.0.0.1:2443/redfish/v1/UpdateService/update
```

Output:
```
{
"error": {
"@Message.ExtendedInfo": [
{
"@odata.type": "#Message.v1_1_1.Message",
"Message": "The request failed due to an internal service error. The service is still operational.",
"MessageArgs": [],
"MessageId": "Base.1.19.InternalError",
"MessageSeverity": "Critical",
"Resolution": "Resubmit the request. If the problem persists, consider resetting the service."
}
],
"code": "Base.1.19.InternalError",
"message": "The request failed due to an internal service error. The service is still operational."
}
```
