 Change check in BP_Friends_Friendship::check_is_friend().

 In BP2.5, we introduced a new friendship caching mechanism that created a
 new cache item containing all of a user's friendships. This approach
 worked well on sites with fewer friendships per user, but caused cache
 access issues on sites with lots of friendship connections.

 This update replaces the cache-intensive change to
 `BP_Friends_Friendship::check_is_friend()` with a return to a single
 lookup to determine friendship status between two users. To minimize SQL
 lookups, individual friendships are now cached, and a new cache-warming
 function has been added to bulk update these new cache items:
 `BP_Friends_Friendship::update_bp_friends_cache()`.

 Props januzi_pl, boonebgorges, r-a-y, djpaul, dcavins.

 Fixes #7436.
