Worker sync utility (#1511)

* patched an issue with wasmoon randomly asking to resolve proxy references * simplified pyodide and micropython dance by grouping their common utilities together * created an integration test around a worker to main thread input between MicroPython and Lua * commented some weird bugs / funny behaviors around both MicroPython and Pyodide * other minor clean ups
