```
wasm-linker: implement the __heap_end symbol

When any of the object files reference the __heap_end symbol, we will
create it as a synthetic symbol. The symbol only exists within the
linker and will not be emit within the binary as it's solely used for
relocations. The symbol represents where the heap ends, so allocators
can determine whether to allocate a new page or not.
