Add experimental support for Emscripten JSPI
...which I've seen fundamentally working when building with recent emsdk
against
recent Qt6 trunk (and including <https://github.com/qt/qtbase/pull/108>
"Update
the check for WebAssembly JSPI support") and running on recent Chrome (with
JSPI
enabled under <chrome://flags/>)
