[pytorch][codegen] migrate gen_annotated_fn_args.py to new codegen model (#47745) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/47745 This is a relatively small codegen. Reintroduced 'simple_type' to preserve old codegen output. It depends on some methods defined in gen_python_functions.py - next PR will clean up the remaining Declarations.yaml methods in gen_python_functions.py. Confirmed byte-for-byte compatible with the old codegen: ``` Run it before and after this PR: .jenkins/pytorch/codegen-test.sh <baseline_output_dir> .jenkins/pytorch/codegen-test.sh <test_output_dir> Then run diff to compare the generated files: diff -Naur <baseline_output_dir> <test_output_dir> ``` Differential Revision: D24885068 Test Plan: Imported from OSS Reviewed By: ezyang Pulled By: ljk53 fbshipit-source-id: c0fbd726bcc450c3c7fe232c23e5b31779d0b65f
