ci: fix xpu skip condition for test_model_parallel_beam_search (#35742)

`return unittest.skip()` used in the `test_model_parallel_beam_search` in
skip condition for xpu did not actually mark test to be skipped running
under pytest:
* 148 passed, 1 skipped

Other tests use `self.skipTest()`. Reusing this approach and moving the
condition outside the loop (since it does not depend on it) allows to skip
for xpu correctly:
* 148 skipped

Secondly, `device_map="auto"` is now implemented for XPU for IPEX>=2.5 and
torch>=2.6, so we can now enable these tests for XPU for new IPEX/torch
versions.

Fixes: 1ea3ad1 ("[tests] use `torch_device` instead of `auto` for model testing (#29531)")
