Temporarily add nullptr checks in frontend

The fuzzer is able to trigger nullptr reads by failing to create objects
and then using the resulting nullptr in other operations. The proper fix
is to implement WebGPU error handling where creation failure returns a
valid but "error" object.

However implementing this error handling is a lot of work, so in the
meantime we use nullptr checks in relevant places to fix the fuzzer
issue. These checks will be removed once the error handling is changed.
