Fran Bull 1bd1b387b2 appc: add flag shouldStoreRoutes and controlknob for it
When an app connector is reconfigured and domains to route are removed,
we would like to no longer advertise routes that were discovered for
those domains. In order to do this we plan to store which routes were
discovered for which domains.

Add a controlknob so that we can enable/disable the new behavior.

Brad Fitzpatrick 7b34154df2 all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89]
First we had Capabilities []string. Then
https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a
superset of Capabilities. Except we never really finished the
transition inside the codebase to go all-in on CapMap. This does so.

Notably, this coverts Capabilities on the wire early to CapMap
internally so the code can only deal in CapMap, even against an old
control server.

In the process, this removes PeerChange.Capabilities support, which no
known control plane sent anyway. They can and should use
PeerChange.CapMap instead.

Marwan Sulaiman 2dc0645368 ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

taildrop: implement asynchronous file deletion (#9844)
File resumption requires keeping partial files around for some time,
but we must still eventually delete them if never resumed.
Thus, we implement asynchronous file deletion, which could
spawn a background goroutine to delete the files.

We also use the same mechanism for deleting files on Windows,
where a file can't be deleted if there is still an open file handle.
We can enqueue those with the asynchronous file deleter as well.

taildrop: add logic for resuming partial files (#9785)
We add the following API:
* type FileChecksums
* type Checksum
* func Manager.PartialFiles
* func Manager.HashPartialFile
* func ResumeReader

The Manager methods provide the ability to query for partial files
and retrieve a list of checksums for a given partial file.
The ResumeReader function is a helper that wraps an io.Reader
to discard content that is identical locally and remotely.
The FileChecksums type represents the checksums of a file
and is safe to JSON marshal and send over the wire.

taildrop: improve the functionality and reliability of put (#9762)
Changes made:
* Move all HTTP related functionality from taildrop to ipnlocal.
* Add two arguments to taildrop.Manager.PutFile to specify
  an opaque client ID and a resume offset (both unused for now).
* Cleanup the logic of taildrop.Manager.PutFile
  to be easier to follow.
* Implement file conflict handling where duplicate files are renamed
  (e.g., "IMG_1234.jpg" -> "IMG_1234 (2).jpg").
* Implement file de-duplication where "renaming" a partial file
  simply deletes it if it already exists with the same contents.
* Detect conflicting active puts where a second concurrent put
  results in an error.
