[Draft] Extract reflection helper to reduce duplicate code

[mengyanshou]

#6492

I’ve only wrapped the reflection-related code into a utility class for now, and updated Workarounds to reduce duplicated reflection logic. There are still some temporary logging statements, which I’ll remove after testing is complete.

The utility currently provides:

• createInstance
• setField
• getField
• invokeMethod
• invokeMethodWithParam

So far this has only been tested on a few emulators. I added log output at each modified call site to verify everything works correctly.

Next work:

• Test on more emulators
• Improve the code and add comments
