Deleted the as_string ASR and HIR dumps

Fixes #2021, #2022
Deleted Parser::debug_dump_ast_output, removed any functions that called
it i.e Session::dump_ast and Session::dump_ast_expanded, and any
associated items.

Made it so that when you use the dump option "expanded" it dumps the
pretty ast only.

gcc/rust/ChangeLog:

	* parse/rust-parse-impl.h (Parser::debug_dump_ast_output): Removed this funtion.
	* rust-session-manager.cc (Session::enable_dump): Removed else if (arg == "parse").
	(Session::compile_crate): Removed calls of dump_ast and dump_ast_expanded.
	(Session::dump_ast): Removed this function.
	(Session::dump_ast_expanded): Removed this function.
	* rust-session-manager.h (struct CompileOptions): Removed the PARSER_AST_DUMP option.
