Create bytecode handlers and add them to the builtins table

This doubles the size of the snapshot since it creates all of the
handlers twice (and it doesn't use any of these new ones). However it's
all behind a flag.

For now all bytecode handlers are marked as being not Isolate
independent to prevent snapshot creation failures.
