refactor(cli): replace loading file for --config flag with generic structure (#10481)

Currently file passed to --config file is parsed using TsConfig structure
that does multiple things when loading the file. Instead of relying on that
structure I've introduced ConfigFile structure that can be updated to
sniff out more fields from the config file in the future.
