PCI/AER: Report CXL or PCIe bus type in AER trace logging

The AER service driver and aer_event tracing currently log 'PCIe Bus Type'
for all errors. Update the driver and aer_event tracing to log 'CXL Bus
Type' for CXL device errors.

This requires that AER can identify and distinguish between PCIe errors and
CXL errors.

Introduce boolean 'is_cxl' to 'struct aer_err_info'. Add assignment in
aer_get_device_error_info() and pci_print_aer().

Update the aer_event trace routine to accept a bus type string parameter.
