port the src of graphql-js

[kfly8]

This issue is porting the src directory of graphql-js.
https://github.com/graphql/graphql-js/tree/main/src

How to work

If you have a file you want to port, write the name beside the file.

Please write tests as well as porting. Of course, the tests written in graphql-js should be ported, and in addition to that, please aim for 100% C0 coverage to improve the quality of the code.
