Merge feature flags related to new CI minutes tracking

Merge `ci_minutes_use_notification_level` (for alerting
about remaining minutes) and `ci_reset_purchased_minutes_lazily`
(for recaculating additional CI minutes) under the existing
`new_monthly_ci_minutes_enabled` feature flag which will
control them all.

This simplifies the rollout and keeps the behavior consistent.
