Port pytorch mobile v1.13.0 for SDP 7.1

[eleir9268]

This PyTorch version compiles with (and supports a version of XNNPACK that compiles with) SDP 7.1.

Tests: All pass except,

./c10_typeid_test
[ RUN      ] TypeMetaTest.Names
/home/eleir/gh_workspace/pytorch/c10/test/util/typeid_test.cpp:32: Failure
Expected equality of these values:
  "nullptr (uninitialized)"
    Which is: 3138b430d0
  null_meta.name()
    Which is: {}
[  FAILED  ] TypeMetaTest.Names (21 ms)

It seems like they expect a dependency object's constructor to be invoked without explicitly invoking it when creating null_meta.

Example at https://gitlab.com/qnx/sample-apps/pytorch_classifier_example also succeeds.

NOTE
Many of the tests and my example code fail to lock a mutex and throw a system error on teardown. It doesn't look like I'm going to have much luck debugging it (it seems like the build manually strips symbols somewhere so I can't get a backtrace).
I also have not tested many of the command line options to pytorch, i.e. BUILD_LITE_INTERPRETER=OFF, TRACING_BASED=ON, USE_LIGHTWEIGHT_DISPATCH=ON
