Decompose sigmoid to exp+reciprocal to fix U85 TABLE bug

[christine-long-meta]

Summary:
Add DecomposeSigmoidPass that decomposes sigmoid(x) into reciprocal(add(exp(neg(x)), 1)).
This bypasses the broken Vela U85 sigmoid TABLE op by decomposing into
primitive ops whose individual TABLE implementations work correctly on U85.

The pass runs in both the TFA pipeline (before quantization, so exp/reciprocal get
individually annotated for a16w8) and the TOSA pipeline (for FP path).
