Scoru: Wasm: End-to-end test for specific kernel behavior

Goal: Confidence in E2E scenarios using all test kernels.

Depending on kernel this means:

• For compute - some number of kernel_main invocations are completed
• For no_parse_* - parsing results in a stuck state
• For input_output_echo - Rollup Management Protocol parse errors are caught (since blind echoing is not compatible with the protocol)
