🚀 Feature

torch.meshgrid gets an OpInfo test.

Motivation

OpInfo tests are clearly important, especially for operators that have a NumPy/SciPy reference implementation. In particular, we want to enforce compatibility with the NumPy implementation (see #50276).

Pitch

Add an OpInfo test that, among other things, enforces NumPy compatibility.

Alternatives

None: this test is important.

Additional context

This operation is also part of the Python Array API proposal: https://data-apis.org/array-api/latest/API_specification/creation_functions.html#meshgrid-arrays-indexing-xy.
