Bug 1841262 — Add coenrolling features to NimbusBuilder

[jhugman]

Relates to EXP-3623.
Fixes Bug 1841262.

This commit refactors the android-components implementations of NimbusBuilder and Nimbus to accommodate the new getCoenrollingFeatureIds() API.

This API is internal to Application Services, but needs to be passed in via the constructor of the Nimbus object.

This will not build correctly until mozilla/application-services#5697 lands and reaches this repo.

Because this is a breaking change, we've taken the opportunity to do several things here:

• pulled onFetchCallback and onApplyCallback into AS
• make getEnrollingFeatureIds() come from the NimbusBuilder
• move thread creation from the Nimbus object to the NimbusBuilder.

I'm hitting significant issues trying to test this and having to reset a lot of my dev box (larger issues than this PR). Not sure if someone else can pick this up to review but if it's passing the builds tomorrow I'll focus on reviewing the code and approve.
