[WASI] add --no-wasm-opt to fix -03 Cmake failure

[pavelsavara]

CMake Error at C:/Dev/runtime/src/native/external/zlib-ng/CMakeLists.txt:556 (message):
    sizeof(void *) is neither 32 nor 64 bit

Is caused by wasm-opt on local PATH being triggered when CMake configures itself for zlib-ng.
Because it uses -O3
