* wiggle: no longer need to guard wasmtime integration behind a feature this existed so we could use wiggle in lucet, but lucet is long EOL * replace wiggle::Trap with wiggle::wasmtime_crate::Trap * wiggle tests: unwrap traps because we cant assert_eq on them * wasi-common: emit a wasmtime::Trap instead of a wiggle::Trap formally add a dependency on wasmtime here to make it obvious, though we do now have a transitive one via wiggle no matter what (and therefore can get rid of the default-features=false on the wiggle dep) * wasi-nn: use wasmtime::Trap instead of wiggle::Trap there's no way the implementation of this func is actually a good idea, it will panic the host process on any error, but I'll ask @mtr to fix that * wiggle test-helpers examples: fixes * wasi-common cant cross compile to wasm32-unknown-emscripten anymore this was originally for the WASI polyfill for web targets. Those days are way behind us now. * wasmtime wont compile for armv7-unknown-linux-gnueabihf either
