cxl/events: Update DRAM Event Record to CXL spec rev 3.1

CXL spec 3.1 section 8.2.9.2.1.2 Table 8-46, DRAM Event Record has updated
with following new fields and new types for Memory Event Type, Transaction
Type and Validity Flags fields.
1. Component Identifier
2. Sub-channel
3. Advanced Programmable Corrected Memory Error Threshold Event Flags
4. Corrected Memory Error Count at Event
5. Memory Event Sub-Type

Update DRAM events record and DRAM trace event for the above spec
changes. The new fields are inserted in logical places.
Includes trivial consistency of white space improvements.

Example trace print of cxl_dram trace event,
