  [MLIR][TOSA-Linalg] Fix rescale lowering for unsigned input zp (#138313)

Lowering of tosa.rescale to Linalg unconditionally sign-extend the input
zero-point value, even when unsigned_input is true. This commit refactor
zeropoint handling to share the same logic between input and output
zeropoint.
