Optimizer: crash when overflowing

Not sure this is related to #5753.
Up stream report: https://projects.blender.org/blender/blender/issues/144614

Optimizing [48744-0x000001d18b9e86a0-0x81098.dmp](https://github.com/user-attachments/files/21852550/48744-0x000001d18b9e86a0-0x81098.dmp) crashes. This is related to the number of object ids it requires during optimization.

```
spirv-opt.exe 48744-0x000001d18b9e86a0-0x81098.dmp -O -o opt.spv
```

To fix this the next commands are needed

```
spirv-opt.exe 48744-0x000001d18b9e86a0-0x81098.dmp --max-id-bound=99999999 -O -o bad.spv --compact-ids
```

However as we use shaderc as a frontend we don't have access to these parameters.

I would expect that the optimizer would not crash but would be able to normally exit. This way shaderc could be able to report this and Blender would be able to replace the shader with a default.
