  [JSC] Make WEBASSEMBLY_SIGNALING_MEMORY hard requirement for WebAssembly
https://bugs.webkit.org/show_bug.cgi?id=252517
rdar://105621940

Reviewed by Mark Lam.

Now, all wasm platforms have signaling memory implementation. And signaling memory
is part of wasm shared memory. Thus, we should make this mandatory for wasm implementation.
This patch makes WEBASSEMBLY_SIGNALING_MEMORY hard requirement for wasm. And remove WEBASSEMBLY_SIGNALING_MEMORY
flag.
