src: enhance feature access CHECKs during bootstrap

This adds `CHECK`s verifying that bootstrapping has finished
before environment variables are accessed or handles/requests
are created. The latter complements a pair of existent checks,
but fails earlier and thus gives information about the call
site, effectively addressing the TODO comment there.
