Description
Feature or enhancement
Proposal:
When disassembling code object with --show-caches argument its hard to tell right away what is 1st cache entry (counter) value which is useful while debugging. Proposing to add this info to the disassembly of this opcode.
Example:
Instead of current disassembly:
CACHE 0 (counter: 99)
display:
CACHE 0 (counter: 99 (value: 6, backoff: 3))
Has this already been discussed elsewhere?

Research direction
Start with Python's disassembly path for code objects using the --show-caches argument, focusing on how the CACHE opcode currently displays its counter. Determine where the counter value and backoff are formatted, then verify that the disassembly shows both values in the proposed wording. The issue links PR gh-128296, so check that work before starting.
