Goal: Enable using C++ classes to AOT compile models for MLGO.
This commit introduces a transformation pass that converts standalone
`emitc.func` operations into `emitc.class `structures to support
class-based C++ code generation for MLGO.
Transformation details:
- Wrap `emitc.func @func_name` into `emitc.class @Myfunc_nameClass`
- Converts function arguments to class fields with preserved attributes
- Transforms function body into an `execute()` method with no arguments
- Replaces argument references with `get_field` operations
Before: emitc.func @Model(%arg0, %arg1, %arg2) with direct argument
access
After: emitc.class with fields and execute() method using get_field
operations
This enables generating C++ classes that can be instantiated and
executed as self-contained model objects for AOT compilation workflows.
