As we roll out more PRs that migrate to `ts_project`, we need to make
sure that we don't break existing `tsec` targets. This PR copies the
original `tsec` Starlark code and adjusts it to work with the interop.
Note that we don't patch as this would unnecessarily complicate this
file that only exists during migration. Long-term, after migration, we
either need to consider switching to the new ESLint plugin that is being
worked on (I'm in contact with the team), or we send a CL to update the
Tsec Starlark code to keep our changes minimal and avoid scope increase.
