wasm: set ALLOW_MEMORY_GROWTH for multi-threaded builds
Unify the settings for single-threaded and multi-threaded builds;
Qt now always enables heap growth by default.
This means we don't have to reserve a large (1GB) fixed memory
size, but can instead set the smaller (50 MB) initial memory size,
like the single-threaded build does.
Enabling threads + memory growth can potentially cause
a performance regression when accessing heap memory from
JavaScript (https://github.com/WebAssembly/design/issues/1271).
We leave it for the application to decide if this applies,
and if the switch to fixed memory should be made.
