[ci] Add cache cleanup workflow (#32675)

> Caches have branch scope restriction in place. This means that if caches for a specific branch are using a lot of storage quota, it may result into more frequently used caches from default branch getting thrashed. For example, if there are many pull requests happening on a repo and are creating caches, these cannot be used in default branch scope but will still occupy a lot of space till they get cleaned up by eviction policy. But sometime we want to clean them up on a faster cadence so as to ensure default branch is not thrashing. https://github.com/actions/cache/blob/main/tips-and-workarounds.md#force-deletion-of-caches-overriding-default-cache-eviction-policy --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).
