[pytorch][tensorexpr] Make gtest-style macros in tests match actual gtest signatures (#44861)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/44861
We were redefining things like ASSERT_EQ to take a _VA_ARGS_ parameter, so compiling these files with gtest (instead of pytorch's custom python-based cpp test infra) fails.
Test Plan: buck build //caffe2/test/cpp/tensorexpr
