Remove BIONEMO-2840 sm120 fused attention workarounds

The THD implementation for fused attention on sm120 (Blackwell) is now
available in Transformer Engine, so these workarounds are no longer needed.

Removes:
- pytest.xfail guards for sm120 in test_modeling_common.py (6 files)
- monkeypatch.setenv("NVTE_FUSED_ATTN", "0") blocks in esm2 recipe tests
- Unused monkeypatch parameters and torch import where applicable
