Move to ExecuTorch 1.5.1 - #25

Conversation
The PyTorch::ExecuTorch pack 1.5.1 is in the public pack index and executorch 1.5.1 is on PyPI. It targets torch 2.14.0 (torch_pin.py at the v1.5.1 tag) and keeps torchao 0.18, ethos-u-vela 5.1.0 and tosa-tools 2026.5.0, so requirements-arm-tosa.txt is unchanged. The pack pins in the csolution and the cproject follow, and the generated layer and the RTE context headers name the new pack version. The exported program is 8784 bytes instead of 8832.
