Leases can be force set, but since `Leases` is a `StorageValue`, if a
lease misses its sale rotation in which it should expire, it can never
be cleared.

This can happen if a lease is added with an `until` timeslice that lies
in a region whose sale has already started or has passed, even if the
timeslice itself hasn't passed.

This solves that issue in a minimal way, with all expired leases being
cleaned up in each sale rotation, not just the ones that are expiring in
the coming region.

TODO:
- [x] Write test

This PR allows Coretime regions to be transferable via XCM.

With the current code, when a user interlaces their region, the end
result will be three regions in the state:
- the non-interlaced region
- first part of the interlaced region
- second part of the interlaced region

The existing implementation retains the non-interlaced region in the
state, leading to a problematic scenario:

1. User 1 acquires a region from the market.
2. User 1 then interlaces this region.
3. Subsequently, User 1 transfers one part of the interlaced regions to
User 2.
Despite this transfer, User 1 retains the ability to assign the entire
original non-interlaced region, which is inconsistent with the fact that
they no longer own one of the interlaced parts.

This PR resolves the issue by removing the original region, ensuring
that only the two new interlaced regions remain in the state.

This PR includes the following fix:
- [x] The `duration` is always set to zero in the `RegionDropped` event.
This is fixed in this PR.

Also added some additional tests to cover some cases that aren't covered
:
- [x] Selling a partitioned region to the instantaneous coretime pool.
- [x] Partitioning a region after assigning it to a particular task.
- [x] Interlacing a region after assigning it to a particular task.
