  Implement JITless Wasm test mode

Reviewed by Keith Miller.

This patch provides a `--useWasmJIT` test mode, which specifically disables JIT for Wasm
functions. This allows us to test JITless Wasm more effectively, since the JS wrappers
will not be slowed down. This can be optionally enabled in `run-javascriptcore-tests`
using the `--jitless-wasm` flag.
