Tom DNetto ec4f849079 tka: implement filesystem-based tailchonk implementation
FS implements Chonk, and given the expected load characteristics (frequent use
of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the
implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

Tom DNetto cca25f6107 tka: implement Chonk type & an in-memory implementation
Chonks are responsible for efficient storage of AUMs and other TKA state.

For testing/prototyping I've implemented an in-memory version, but once we
start to use this from tailscaled we'll need a file-based version.

Tom DNetto 1cfd96cdc2 tka: implement AUM and Key types
This is the first in a series of PRs implementing the internals for the
Tailnet Key Authority. This PR implements the AUM and Key types, which
are used by pretty much everything else. Future PRs:

 - The State type & related machinery
 - The Tailchonk (storage) type & implementation
 - The Authority type and sync implementation
