Add support for IsSomehowAffectedByAtomics SPIR-V variable query

[artem-lunarg]

This will improve shader access heuristics in syncval.

Going to apply the query to entrypoint interface variables to check if any of the following is true:

• variable itself was modified through atomic operation
• variable was indexed by an index that was computed/affected by atomic operations

Query can be more general of how atomics affect variable, not necessarily the above scenarios.
