Build AST nodes when parsing ES6 modules

This introduces the structures in the AST that allow for the extraction
of imports, exports as well as location of tokens.

The ModuleItemList as entry point is special with regards to the
statements (so not import/export declarations) in the sense that the
statement list contained in ModuleItemList::item is not linked yet
between different ModuleItemList instances.
