Add callback to handle memory.grow failures (#2522)

When embedding WAMR, this PR allows to register a callback that is
invoked when memory.grow fails.

In case of memory allocation failures, some languages allow to handle
the error (e.g. by checking the return code of malloc/calloc in C), some
others (e.g. Rust) just panic.
