feat(wasm): add jwt support

[Codelax]

Fix #3112
Added a config passed to the js run function.
Some platform dependent code was moved from core to platform. Will be improved when adding output configuration (termcaps)
Added a jshelpers package to handle js values

Had to fix some tests as by moving client creation it showed that ReloadClient skipped the client validation
