Reasons:
* duktape is not maintained
* on macOS it produces a warning: unused function '_duk_debugger_attach'
(this slows down incremental builds and pollutes the test logs)
Why goja?
Geth has migrated some parts to goja (console and clef signer tool),
although not migrated tracers yet.
* fix isPrecompiled() native function
* recursion limit test is obsolete
