Add support for int16 data type and int64 biases/accumulators in the TFLite frontend. Adjusts TFLite tests to cover int16 convolutions and element-wise; Fixes a minor typo negtive->negative in the element-wise tests.

Looks good, thanks for adding the int16 support @leandron! Do you know if there any int16 models around by any chance we could test?

Looks good to me, few nits... Great job for getting int16 mobilenet and conv2d tests running, I think it's a really good improvement to our frontend infra!
