e23d159b - [PyTorch][caffe2] Add CAFFE2_{DECLARE,DEFINE}_KNOWN_TYPE (#83707)

[PyTorch][caffe2] Add CAFFE2_{DECLARE,DEFINE}_KNOWN_TYPE (#83707) It looks like we aren't getting inlining for the defined `_typeMetaData` functions from CAFFE_KNOWN_TYPE and there's some cost associated with that. I added new macros that fix this problem; I will migrate to them in a follow-up after I get buy-in from reviewers.
