Function cabi_realloc

embedding/embedding.cpp:141–148

This MUST override the StarlingMonkey core cabi_realloc export NOTE: You *should* avoid external host calls during realloc (ex. using the LOG macro to log a message), as this is a condition under which the component may be marked to prevent leaving (doing a new host call). see: https://github.com/bytecodealliance/wasmtime/blob/aec935f2e746d71934c8a131be15bbbb4392138c/crates/wasmtime/src/runtime/
