Add PCIe Slot information to PCIeDevice schema

To align with Redfish's transition from using the PCIeSlot schema to
including the Slot within the PCIeDevice schema, this commit adds PCIe
Slot information to the PCIeDevice schema. The corresponding PCIe Slot
is retrieved using the 'contained_by' association, which establishes a
link from the PCIeDevice object to the PCIeSlot object. If there is no
PCIeSlot associated with the PCIeDevice, the Slot properties will not
be returned.

Directed associations, ‘containing’ and ‘contained_by’, are used to
establish a link between PCIeDevice and PCIeSlot. The 'containing'
association establishes a link from a PCIeSlot to the PCIeDevice it
contains, while the 'contained_by' association establishes a link from
a PCIeDevice to the PCIeSlot that contains it.

Additionally, this commit refactors the PCIeDevice schema to improve
its structure, readability, and adherence to best practices.
