[PM-11869] Adjust CollectionService to be reactive to keys being available

[eliykat]

https://bitwarden.atlassian.net/browse/PM-11869

📔 Objective

Currently, CollectionService tries to decrypt collections as soon as they're available from state, without organization keys necessarily being available. This can cause decryption errors.

This PR refactors CollectionService so that it uses reactive data for both collection state and org keys and only decrypts once both are available.

This code is fairly dense, so a brief explanation of changes:

1. change the DECRYPTED_COLLECTION_DATA_KEY definition to take a different observable as its input, instead of the encrypted state
2. pass both collectionData and the orgKeys to the getDerived call
3. change the decryptMany method signature to optionally accept keys that are passed in
