[SYCL][L0] Fix BDF format on PCI query (#6011)

The PCI address currently reported by the L0 backend does not correctly
report domain, bus, device, and function as hexadecimal values. This
commit changes the reported format to use convert the values hexadecimal
representation. Additionally it also pads the values with leading zeros.
