candidateTSConfigRootDirs: stores candidate root directories insidetypescript-estree, exposed viaadd*,clear*, andget* functions
- Theget*,getInferredTSConfigRootDir, will throw an error if multiple candidates have been populated. It's only called bycreateParseSettings if notsconfigRootDir was explicitly provided.
getTSConfigRootDirFromStack: given a call stack, gets the candidate directory hosting an ESLint config file -- if it can be found
createConfigsGetters: wraps the configs intypescript-eslint with getters that pass the result ofgetRootDirFromStack tocandidateTSConfigRootDirs

The result is that using any configs liketseslint.configs.recommendedTypeChecked will attempt to populate a candidatetsconfigRootDir for parse settings.
