d014772b - [Profiler] Store Input shapes, dtypes, and metadata into flat AppendOnlyList (#74241)

[Profiler] Store Input shapes, dtypes, and metadata into flat AppendOnlyList (#74241) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/74241 Adds the following changes: - During collection, replaces the vector of vector of int shapes, and vector of string dtypes. Instead pack the IValue details into InputOutputEncoder as flat AppendOnlyLists. - This will save each IValue with a enum tag, metadata holding its dim and dtype, and the shapes. - During Post-Processing, re-construct the vectors that are originally expected (struct Inputs).
