Adds an optional dbcrypt wrapper around gitsshkeys.private_key. The
column is encrypted on insert and update through enterprise/dbcrypt when
external token encryption is configured, and decrypted on read.
A new private_key_key_id column references
dbcrypt_keys(active_key_digest) so revocation safety is enforced by the
existing foreign key. Rows with a NULL key_id stay plaintext and remain
readable. Existing plaintext rows can be backfilled by running `coder
server dbcrypt rotate`.

Add dbcrypt support for user secret values. When database encryption is
enabled, secret values are transparently encrypted on write and
decrypted on read through the existing dbcrypt store wrapper.
- Wrap `CreateUserSecret`, `GetUserSecretByUserIDAndName`,
`ListUserSecretsWithValues`, and `UpdateUserSecretByUserIDAndName` in
enterprise/dbcrypt/dbcrypt.go.
- Add rotate and decrypt support for user secrets in
enterprise/dbcrypt/cliutil.go (`server dbcrypt rotate` and `server
dbcrypt decrypt`).
- Add internal tests covering encrypt-on-create, decrypt-on-read,
re-encrypt-on-update, and plaintext passthrough when no cipher is
configured.

Updates docs that talk about what db fields we encrypt. We've recently added `crypto_keys.secret` to the list, but didn't add it to the docs.
