[LL FIR] KT-57455 Avoid creating optional annotation class providers

- An `OptionalAnnotationClassesProvider` only needs to be created if the
  package part provider may even have optional annotation classes.
- In the IDE case, the package part provider never provides optional
  annotation classes, so especially in the IDE, we can avoid a lot of
  useless symbol providers with this.
