Rename NODE_ARRAY to NODE_LIST to reflect its actual use cases

and NODE_ZARRAY to NODE_ZLIST.

NODE_ARRAY is used not only by an Array literal, but also the contents
of Hash literals, method call arguments, dynamic string literals, etc.
In addition, the structure of NODE_ARRAY is a linked list, not an array.

This is very confusing, so I believe `NODE_LIST` is a better name.
