fix(wasm-c-api): Do not clone stack frames if there's no trap (#3008)

Browse Source 
When running the wasi-threads no_pthread sample, the assert was failing
on `src->num_elems != 0` in debug mode, it is because that the exception
is `proc_exit`, there is no trap (the execution didn't fail, no stack frames):
