feat: check usb/pci/gpu resource name (backport #100)

[mergify]

IMPORTANT: Please do not create a Pull Request without creating an issue first.

Problem:
When creating or updating a non-existed pci/usb resource name, it's allowed. Besides, vGPU device is not checked either.

Solution:
We should check .DeviceName in VM spec while creating or updating. BTW, vGPU device is in the other field, so we need to check it in spec.template.domain.devices.gpus.

.DeviceName means resource name in k8s.

Related Issue:
harvester/harvester#6542

Test plan:

Test PCI Device

1. Enable pcidevices-controller Add-on
2. Enable one of PCI devices
3. Create a VM and attach previous PCI device
4. Click "Edit as YAML" button to manually edit YAML file, then click "Create" button.
5. Modify the .DeviceName in the spec.template.domain.devices.hostDevices.

If you're not sure how to do it, please refer following demo recording.

pcidevice.mov

Test USB Device

1. Enable pcidevices-controller Add-on
2. Enable one of USB devices
3. Create a VM and attach previous USB device
4. Click "Edit as YAML" button to manually edit YAML file, then click "Create" button.
5. Modify the .DeviceName in the spec.template.domain.devices.hostDevices.

If you're not sure how to do it, please refer following demo recording.

Since v1.3 doesn't have USB device, so I remove most USB device codes.

okay ... I thought we need to backport this. It turns out the labels are used to test harvester/bot ...
