Make pretty-printing of graphs available to codeql query run

codeql test run has a nice pretty-printer for graph queries (i.e. for the PrintIR query for cpp).
It would be great to have the option to run queries using codeql query run and then get the output pretty-printed.
The results of PrintIR.ql are otherwise not that helpful.

首先，使用 issue 中提到的 C++ `PrintIR.ql` 示例，比较 `codeql test run` 如何美化打印图查询结果与 `codeql query run` 的输出。完成标准是 `codeql query run` 提供一个选项，为图查询生成同样有用的美化打印输出。
