This way we avoid repeating the same implementation in each inherited type, as they can just use the parent default. I think this also would help enforce that `::getExtensions()` is not abused as any custom implementation of `::getExtensions()` would have to be explicit.

Good idea, done. I wanted to preserve the existing API but didn't realize that all these `::getExtensions` functions in derived classes only shadow the main definition in `SPIRVType`.
