  [JSC] Disable Options::useWasmFastMemory on PlayStation
https://bugs.webkit.org/show_bug.cgi?id=279652

Reviewed by Keith Miller.

Instantiating wasm memory on PS (via the call `new WebAssembly.Memory({ initial: 1 })` or the instruction `(memory 1)`)
causes a crash in Gigacage::tryAllocateZeroedVirtualPages. It seems we should keep useWasmFastMemory off on our platform.

(Less than ideal to have this be a platform-specific guard, but I'm not sure what the right-sized condition would be.)
