gpg: Improve speed of secret key listing.

With this change we first ask the agent for a list of all secret
keygrips and use that list instead of asking the agent for each public
key.  Speeds up my "gpg -K" with a lot of secret and public keys by
more than 25%.

gpg: Add new command keytotpm to convert a private key to TPM format
* agent/command.c (cmd_keytotpm): New.
(agent/command.c): Register new command KEYTOTPM.
* g10/call-agent.c (agent_keytotpm): New.
* g10/keyedit.c (cmdKEYTOTPM): New command "keytotpm".
(keyedit_menu): Implement.

--

The plumbing is done in two parts: the agent is modified to understand
a KEYTOTPM assuan command taking the key grip as an argument.  This
simply obtains the key s expression and calls the existing writeky
diversion to the tpm2daemon.  The daemon reponds with the TPM
conversion of the key and that key is then stored in the keyfile as a
shadowed-private-key with "tpm2-v1" type.

To effect the conversion, all the user does from gpg --edit-key is
select which private key they wish to move (or move the primary if no
key is selected) and type keytotpm.  The conversion to TPM form is
instantaneous and once converted, the actual key cannot be recovered,
meaning that if you want your gpg key to move to a new laptop you must
keep an unconverted backup copy in a safe location.

When you do a list command, all TPM keys show up as

     card-no: TPM-Protected

The key is stored encrypted to the TPM2 storage seed and since each
TPM has a unique seed, only the single TPM contained in your laptop
can now read the key.  This means you cannot simply copy the shadowed
key file over to a new laptop, you must copy over the backup copy and
then convert it to TPM form on the new laptop.

To decomission your laptop, execute a tssclear command which
regenerates the storage seed and effectively shreds all keys.  Note
when you have done this *every* TPM2 shadowed private key becomes
unreadable by any TPM and all are effectively destroyed.

Key generation direct from the card used to work for all cards except
the OpenPGP cards. The key generation from card using an OpenPGP card
is special because the fingerprint is stored on the card and we must
make sure that the newly created key has the same fingerprint.  This
requires that we take the key creation date as stored on the card into
account.

Along with the recent change in gpg-agent this change also fixes a
problem with existing stub files.

Note that with a key take from a card the self-signature are created
with the current time and not the creation time.  This allows to
better distinguish keys created using the same card.

key from the key on the card.

There are still a couple of problems related to the agent which
creates the stub key and may run into problems if creating a second
key from the card.  This will be fixed in a future patch.

We already have $AUTHKEYID to locate the keyref of the key to be used
with ssh.  It will also be useful to have default keyref for
encryption and signing.  For example, this will allow us to repalce
the use of "OPENPGP.2" by a app type specific keyref.

Note that this new menu 14 is always displayed.  The usage flags can
be changed only in --expert mode, though.  Creating and using signing
keys works but decryption does not yet work; we will need to tweak a
couple of other places for that.  Tested with a Yubikey's PIV app.
