The default value for `run_single_threaded` was wrongly specified in the .cpp file instead of the header, breaking C++-side instantiation of `AOTIModelPackageLoader` with no arguments. This PR fixes this and adds a test for the use case of running with `AOTIModelPackageLoader` instead of `AOTIModelContainerRunner` on the C++ side.

Summary: Tighten the AOTIModelContainerRunner::run interface to take a const vector of at::Tensor, which 1) makes it clear that the runner will not modify the input tensor vector; 2) runner will be able to take a temp vector of tensors as the input.

Summary: In AOTInductor generated CPU model code, there can be direct references to some aten/c10 utility functions and data structures, e.g. at::vec and c10::Half. These are performance critical and thus it doesn't make sense to create C shim for them. Instead, we make sure they are implemented in a header-only way, and use this set of tests to guard future changes.
There are more header files to be updated, but we will do it in other followup PRs.
