Subject: [PATCH] [compiler:babel] Don't read config files when not running as
 part of user's pipeline

When the user app has a babel.config file that is missing the compiler,
strange things happen as babel does some strange merging of options from
the user's config and in various callsites like in our eslint rule and
healthcheck script. To minimize odd behavior, we default to not reading
the user's babel.config

Fixes #29135
