add iodebug support for all rings complement #64 (#66)
This PR is for "I/O Interface to Bochs Debugger" from ring3 (port range:
**0x8A00 - 0x8A01**)

PR #64 was for E9 HACK (port **0xE9**)

By enabling the iodebug's 'all_rings' option, you can utilize the port
I/O Interface to Bochs Debugger from ring3. This PR allows the code
running inside Bochs (ring3) to monitor memory ranges, trace individual
instructions, and observe register values during execution.


https://bochs.sourceforge.io/doc/docbook/development/debugger-advanced.html

IMO very useful for:

- user-mode sandbox (ex Cuckoo)
- malware analysis
- API/SYSCALL hook/monitor from ring3
- automation + instrumentation from user mode code
...

A complement for PR #64

**This PR is 100% backward compatibility**

RINGS](https://github.com/bochs-emu/Bochs/assets/9882181/6308ad0f-c189-43f3-a92b-dccde3542ad6)

btw, @stlintel I'm not certain about:
- if misc is the ideal location for this.. should I create a new
iodebug-option for this?
- should I remove the #if in 'new bx_param_bool_c'?
- the new .bochsrc entry makes sense for you?
