Add -fexceptions to quantized kernel generated libs (pytorch#14962)

Summary:

Added compiling with `-fexceptions` since quantized kernels have exception based code in them. Example error:
```
buck-out/ABC/gen/fbsource/6e53edb0a9a0d828/xplat/executorch/kernels/quantized/__generated_lib_combined__/out/RegisterCodegenUnboxedKernelsEverything.cpp:77:44: error: exception handling disabled, use '-fexceptions' to enable
   77 |             } catch (const std::exception& ex) {
      |           
```
This means the generated code uses exceptions in its code, so we should explicitly flag it to the compiler via the relevant BUCK targets.
