...by making the general UNO -> C++ function call case work (modulo handling exceptions, which I'll look into later). Wasm call_indirect unfortunately needs to statically know the call target's signature, so we statically need to know all possible signatures. So introduce wasmcallgen helper to scan the existing UNOIDL API upfront and generate the relevant callvirtualfunction-wrapper.cxx and callvirtualfunction-inst.s code. (The good thing is that the number of different signatures is somewhat limited, each parameter can only be one of i32, i64, f32, or f64. So even if 3rd-party extensions bring along new UNOIDL interface methods, chances are relatively high that the signatures needed for them would already be covered by the existing ones.) Testing this can nicely be done in unotest/source/embindtest/embindtest.js via css.script.Invocation (which internally exercises the relevant code). (Instead of adding individual org.libreoffice.embindtest.StructLong/String etc., it would be nicer to introduce some polymorphic StructOne<T>, but the Emind UNO binding does not support polymorphic structs, so the embindtest.js code would not work.)
