fix the incorrect merge of profiling information of two tensor types for the same value (#36806)
Summary:
as a part of moving to the dynamic shapes we are now passing `frame_id` to each profiling callback. The implementation of that requires copying profiling callbacks into Interpreter, so `first`s are actually different for every run. The dynamic shapes merging algorithm won't be using `first`, but in the meantime, while we get there, this should be a good enough fix.
