Move legacy thread proxying system into seperate source and header. N…
…FC (emscripten-core#19946) This is the first step towards removing the internal use of the old proxying system. The primary user of which is the JS library proxying system. The legacy proxying system is already layered on top of the new proxying system so removing it should be pure win.
