Remove zp subtraction from tensor_read pseudocode
Operators which use the zero-point functionalty for 8-bit integer
processing are updated to do the zero-point subtract in their
pseudocode.
Note that the PAD operator no longer takes a zero point argument,
and instead requires callers to account for the zero point in the
pad_const argument.
