I pushed a completely new implementation for this, building off of @joyeecheung’s #50137. Until that merges in, you can see what this PR adds at https://github.com/GeoffreyBooth/node/compare/vm-flag-callback-2…GeoffreyBooth:node:better-esm-check |

This PR speeds up and simplifies the error path for when users
requireES modules. In particular, the previoushasEsmSyntaxhelper used Acorn to parse the required module’s source code to find ESM syntax. In this refactor, the check moves into C++ and relies on V8 throwing aSyntaxErrorwith one of the error messages that we know are caused by ESM syntax in a module compiled as CommonJS. This allows us to eliminate one use of Acorn from the codebase.This also creates the helper function that #50096 needs.
