  Log Message:
  -----------
  [SPIRV] Use `Op[S|U]Dot` when possible for integer dot product (#115095)

```
- use the new OpSDot/OpUDot instructions when capabilites allow in SPIRVInstructionSelector.cpp
- correct functionality of capability check onto input operand and not return operand type in SPIRVModuleAnalysis.cpp

- add test cases to demonstrate use case in idot.ll
```

Resolves #114632
