spirv-fuzz: Pass to replace int operands with ints of opposite signedness (#3612)

This PR introduces a new fuzzer pass, which:

- finds all integer vectors or constants
- finds or creates the corresponding constants with opposite
  signedness
- records such constants as synonyms of the first ones
- replaces the usages of the original constants with the new ones
  if allowed

Fixes #2677.
