This CL teaches lsp to report `**T` instead of `**invalid type`, `func (badParam) badResult` instead of `func (invalid type) invalid type`, etc. To do that, we need to detect "invalid type" inside any part of a type. I've added typeIsValid() function for that. To simplify type formating code in resolveInvalid(), formatNode function is added that can also format *ast.StarExpr (of any depth). Since we already used AST printer in the same file, I added formatNode function that is now used in both places. While at it, replaced bytes.Buffer to strings.Builder there.
