Zero out memory allocated by wasm-rt 
In release 1.0 of the WebAssembly Specification, it says that all the
bytes in WebAssembly memory need to be initialized to 0 on creation of
the memory, and when memory is grown, the new bytes also need to be
initialized to 0.

It seems this zeroing behaviour is indeed required for the sandbox to
operate correctly. Not zeroing leads to undefined behaviour. This
manifested as a crash that occurred when restarting the libretro core,
but for some reason, only on Emscripten. Not sure why this didn't happen
on other platforms. Even sanitizers weren't able to detect the bug!
