Adonis Ling 16a394da0e [chore](build) Use include-what-you-use to optimize includes (PART III) (#18958)
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.
