Paramatize test_aten_xla_tensor tests

🚀 Feature

Paramatize test_aten_xla_tensor tests. Inspired by #8734 (comment).

Example of a test_aten_xla_tensor tests: test_aten_xla_tensor_1

Motivation

Decrease and simplify the amount of code we have for testing while increasing readability. Right now test_aten_xla_tensor tests are split into 6 distinct files. Each with over 1000 lines each. 2 with over 5000 lines. This makes tests hard to read, and implementing new tests.

Paramatization will hopefully:

1. Significantly decrease the number of lines on the test
2. Significantly increase readability
3. Increase speed for developing tests

Pitch

Collapse tests that are simililar into the same Parameterized test.

Alternatives

There are other paramitization methods for C++ that are less clean than INSTANTIATE_TEST_SUITE_P. We could seek these if they are blockers

Additional context

We should utilize INSTANTIATE_TEST_SUITE_P

While we are at it, we should probably also write somewhere where to write a test (in which of all of these files?)
