From: Shiju Jose <[e-mail]>

CXL spec rev 3.1 section 8.2.9.2.1.1 Table 8-45, General Media Event
Record has updated with following new fields and new types for Memory
Event Type and Transaction Type fields.
1. Advanced Programmable Corrected Memory Error Threshold Event Flags
2. Corrected Memory Error Count at Event
3. Memory Event Sub-Type

The format of component identifier has changed (CXL spec 3.1 section
8.2.9.2.1 Table 8-44).

Update the parsing, logging and recording of general media event for
the above spec changes.

Example rasdaemon log for CXL general media event,
