Support XYZ interface for Location code

Update xyz interface for Location code in ibm-read-parser and vpd-manager
along with com.ibm.path for Location code.

Test Result-
busctl introspect xyz.openbmc_project.Inventory.Manager  /xyz/openbmc_project/inventory/system/chassis/motherboard| grep -e "Location" -e "FC" -e "SE"
