LibJS/Bytecode: Make Bytecode::Interpreter participate in GC marking

Browse source 
Since the relationship between VM and Bytecode::Interpreter is now
clear, we can have VM ask the Interpreter for roots in the GC marking
pass. This avoids having to register and unregister handles and
MarkedVectors over and over.

Since GeneratorObject can also own a RegisterWindow, we share the code
in a RegisterWindow::visit_edges() helper.

~4% speed-up on Kraken/stanford-crypto-ccm.js :^)
