gh-104584: Emit macro expansions to opcode_metadata.h (#106163)

Browse source 
This produces longer traces (superblocks?).

Also improved debug output (uop names are now printed instead of numeric opcodes). This would be simpler if the numeric opcode values were generated by generate_cases.py, but that's another project.

Refactored some code in generate_cases.py so the essential algorithm for cache effects is only run once. (Deciding which effects are used and what the total cache size is, regardless of what's used.)
