Improve build cache strategy

Ripped off from Quarkus.

Here's how it will work:

1. We create a cache entry on push only. Pull requests only restore it.
2. We create a new cache entry every day, prefixed with something like
   2024-10-25.
3. When restoring the cache, we try the entry for the day first
   (2024-10-25) and default to the one for the month (2024-10-*).
   Critically, this means we will build each day's cache based on the
   previous day's cache.
4. Atlas infra uses its own, separate cache entries.
