Add decode of pcie device class
This commit makes two major changes. First, the device class tables
were being decoded incorrectly as LSB-first. This changes them to
MSB-first.
Second, once this value is correct decode the tables to a string name
making it much easier for users to identify a specific device that
caused a PCIe error.
Note: The majority of the mode lookup table was created by LLM. The
entries have been manually reviewed for correctness and completeness.
