wasm: update test runner

This updates the test runner for stage2 to emit to stdout with the passed, skipped and failed tests
similar to the LLVM backend.

Another change to this is the start function, as it's now more in line with stage1's.
The stage2 test infrastructure for wasm/wasi has been updated to reflect this as well.
