node.h: remove NODE_PRELUDE

NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option.
This node is assumed that it must be located immediately under the root
NODE_SCOPE, but this strange assumption is not so good, IMO.

This change removes the assumtion; it integrates the former two nodes by
block_append, and moves compile_option into rb_ast_body_t.
