spirv-fuzz: Ignore specialization constants (#3664)

`FuzzerPassInterchangeSignednessOfIntegerOperands` and `FuzzerPassInterchangeZeroLikeConstants` both included specialization constants when trying to find integer constants with known values. However, this is incorrect behavior because we do not know the value of specialization constants. Furthermore, ConstantManager does not support them, and this led to crashes where we assumed we could look up specialization constants via the ConstantManager.

This change fixes both passes to ignore specialization constants.

Fixes #3663.
