ast: Add difference between attributes

Add a boolean to tell inner and outer attributes ast nodes appart. This
meant refactoring a bit their parsing function.

gcc/rust/ChangeLog:

	* ast/rust-ast.h: Add boolean for differenciation.
	* parse/rust-parse-impl.h (Parser::parse_doc_comment): Change
	function interface to make code cleaner. It should return a body
	instead of the whole attribute.
	(Parser::parse_inner_attribute): Specify the inner status of the
	node.
	(Parser::parse_attribute_body): Change function interface to
	make the code cleaner much like parse_doc_comment.
	(Parser::parse_outer_attribute): Specify outer status of the
	node.
	* parse/rust-parse.h: Update functions prototypes.
