[SR] Enforce checks for resizing of the internal buffer in MemoryPlanner in unit tests (#67941)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/67941
I just found out that due to the round up of the Tensor storage sizes to multiples of 64 bytes, resizing is not actually triggered for a lot of our unit tests (23 OSS, 16 internal). Now they should be all fixed. Also moved a bunch of tests to `test_static_module.cc` so that `test_static_runtime.cc` now only contains operator tests.
From now on, by default if `args2` is passed to `test_static_runtime`, at the end of the second iteration, it would check that the managed buffer's size is bigger than the previous size and enforce that. You can bypass the check for ops with constant output sizes, such as `aten::sum` without `dim` passed in.
