[Yu-Zhewen]

Summary

• bump the pinned rocJITsu revision and simulator cache key to 056c1cc3
• restore MI450 simulator tests fixed by [rocJITsu][gfx1250] v_dual_cndmask_b32 with a vcc_hi selector aborts the emulator ROCm/rocm-systems#10793, #10805, and #10806
• keep deselections associated with upstream issues that remain unfixed

Validation

• cold local setup cloned and built rocJITsu 056c1cc3 in the dedicated MI450 container
• all 11 restored, currently valid tests passed locally
• manual AMD CI run passed, including the full MI450 simulator job
• the preceding cold-cache run successfully completed Install CI task and saved the new cache key
