Reviewed by Don Olmstead.

WebAssembly no longer requires JIT, but it's still incompatible with
cloop, so let's make sure you cannot build with both enabled and set an
appropriate default value for each architecture.

This is my second attempt to land this change. On the first attempt,
r271252@main, I accidentally changed the default value of
ENABLE_WEBASSEMBLY to "NOT". Let's do better this time.
