What does this PR do?

Reverts the manual half-slicing workaround in Flux2SwiGLU.forward back to torch.chunk to fix the regression reported in #14097. The workaround was only added to support the Neuron torch.compile backend, which no longer requires it in their latest beta, so this change carries no downside for Neuron integration.
