Display counter `value` and `backoff` when disassembling `CACHE` opcode

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?

从 Python 针对代码对象的反汇编路径开始，使用 --show-caches 参数，重点关注 CACHE 操作码当前如何显示其计数器。确定计数器值和 backoff 在哪里进行格式化，然后验证反汇编是否按照提议的措辞显示这两个值。该 issue 链接到了 PR gh-128296，因此请在开始之前检查这项工作。
