tint: Unkeyword 'var' template args

Change the address space and access mode in ast::Var from enums
to Expressions. Have the resolver resolve these, like we do for
other template arguments.

As the AST nodes now have identifier expressions, the tint-internal
'in' and 'out' address spaces have been prefixed with underscores to
prevent input code from using this.
