PCI/AER: Add optional logging callback for correctable error
Some new devices such as CXL devices may want to record additional error
information on a corrected error. Add a callback to allow the PCI device
driver to do additional logging such as providing additional stats for user
space RAS monitoring.
For CXL device, this is actually a need due to CXL needing to write to the
CXL RAS capability structure correctable error status register in order to
clear the unmasked correctable errors. See CXL spec rev3.0 8.2.4.16.
