Integer divide is not commonly used, but would have been difficult to

It is challenging to work back from the RESCALE->TABLE->RESCALE
for a simple 8-bit lookup. This adds support to TOSA for a
simple direct 256 entry 8-bit lookup table for the TABLE operator.

The 16-bit interpolated table is still required for a conformant
implementation.

Originally only a pair of input tensors were allowed.
This aligns with what the frameworks do, and simplifies the
translation of frameworks into TOSA and allows compilers
to view the output as a whole.

The aint8 type represented an asymmetrically quantized range.
With the change to move scaling fully into the RESCALE operator,
the aint8 and int8 types didn't have significant differences in
their use with operators. Unifying to a single data type makes
things simpler.
