[TypedFunctionReferences] Enable call_ref in fuzzer, and fix minor misc fuzz bugs (#3401)
* Count signatures in tuple locals. * Count nested signature types (confirming @aheejin was right, that was missing). * Inlining was using the wrong type. * OptimizeInstructions should return -1 for unhandled types, not error. * The fuzzer should check for ref types as well, not just typed function references, similar to what GC does. * The fuzzer now creates a function if it has no other option for creating a constant expression of a function type, then does a ref.func of that. * Handle unreachability in call_ref binary reading. * S-expression parsing fixes in more places, and add a tiny fuzzer for it. * Switch fuzzer test to just have the metrics, and not print all the fuzz output which changes a lot. Also fix noprint handling which only worked on binaries before. * Fix Properties::getLiteral() to use the specific function type properly, and make Literal's function constructor require that, to prevent future bugs. * Turn all input types into nullable types, for now.
