IVGCVSW-6929 Fix for segfault in tflite delegate
* It's possible that a model may have an input entry for bias tensors
but that the index for those is -1. If it's -1 then it's not present.
* Fixed logic error in IsOptionalOperandPresent: it returned false if
it was present and true if it was missing.
