Arm backend: Expand list of ops without quant kernel - #24430

Conversation
The added ops will output fp32 fake tensors, even when the input is int8 which injects floating point tensors in the graph after quant folding. This is usually not enough to fail lowering, but can cause issues under certain conditions such as: - Some node inserts a node without qparams - The decorate_fp32_to_int32 pass sees a cast to int32 that is supposed to be int8->int32. Since neither qparams, nor correct meta is present, an fp to int cast is inserted into an otherwise quantized graph.
