Changes
Gather metatype is removed from input quantizable metatypes
Reason for changes
To prevent FQ propagation through gathers (relevant for the ScadeDotProductAttention quantization):
A quantizer starts to quantize all branches of a gather when propagated up through the gather node. This breaks the logic of quantization: some branches should have FP32 precision, and this propagation is ruining it.
