Add OpInfo for torch.Tensor.__setitem__ (to test prims.copy_with_setitem)

[kshitij12345]

Currently we have a manual test at

lightning-thunder/thunder/tests/test_ops.py

Lines 242 to 253 in 1575797

	def test_setitem():
	def fn(a):
	a[:3] = 2
	return a * 2
	a_ref = torch.ones(5)
	out_ref = fn(a_ref)
	a = torch.ones(5)
	jf = thunder.jit(fn)
	out = jf(a)
	assert_close(a, a_ref)
	assert_close(out, out_ref)

and PR #1322 extends this test.

I think it would be nice if we can leverage the OpInfo infra though I am not sure how it interacts for inplace operations (as currently all ops in opinfo are out-of-place).

We have some infra which uses OpInfo to generate a new list _inplace_opinfo for inplace ops by finding their corresponding inplace version. (Maybe we can directly add the OpInfo for setitem here?)
