DeleteFruVpd:Conditional FRU deletion

This commit adds a check in deleteFruVpd API to prevent deletion of FRUs
which are present and whose presence is handled by external service.

```
Test:
- On Everest system, see fan0 VPD is present on PIM
- Set "Present" property of fan0 to false using busctl
- See fan0 VPD is cleared from PIM
- Set "Present" property of fan0 to true using busctl
- Execute DeleteFruVpd API from vpd-manager D-Bus interface
- DeleteFruVpd fails
- Check VPD of pcie_card2 using vpd-tool and see it is present
- Execute deleteFruVpd on pcie_card2 and see it is successful
```
