Alex Chan e1dd9222d4 ipn/ipnlocal, tka: compact TKA state after every sync
Previously a TKA compaction would only run when a node starts, which means a long-running node could use unbounded storage as it accumulates ever-increasing amounts of TKA state. This patch changes TKA so it runs a compaction after every sync.

Alex Chan 1723cb83ed ipn/ipnlocal: use an in-memory TKA store if FS is unavailable
This requires making the internals of LocalBackend a bit more generic,
and implementing the `tka.CompactableChonk` interface for `tka.Mem`.

Alex Chan 4673992b96 tka: created a shared testing library for Chonk
This patch creates a set of tests that should be true for all implementations of Chonk and CompactableChonk, which we can share with the SQLite implementation in corp.

It includes all the existing tests, plus a test for LastActiveAncestor which was in corp but not in oss.
