This CL extends unified IR to handle creating wrapper methods. There's relatively little about this code that's actually specific to unified IR, but rewriting this logic allows a few benefits: 1. It decouples unified IR from reflectdata.methodWrapper, so the latter code can evolve freely for -G=3's needs. This will also allow the new code to evolve to unified IR's wrapper needs, which I anticipate will operate slightly differently. 2. It provided an opportunity to revisit a lot of the code and simplify/update it to current style. E.g., in the process, I discovered #46903, which unified IR now gets correctly. (I have not yet attempted to fix reflectdata.methodWrapper.) 3. It gives a convenient way for unified IR to ensure all of the wrapper methods it needs are generated correctly. For now, the wrapper generation is specific to non-quirks mode.
