Because the only available version of wasm ABI did not allow
freeing any allocated memory, a new version of the ABI is
introduced. In this version, the host is required to export
_scylla_malloc and _scylla_free methods, which are later used
for the memory management.

The ABI of wasm UDFs changed since the last time the documentation
was written, so it's being update in this patch.
