Fixes#30235
If the key id "front" byte has a single digit, `%X` is missing the 0
prefix.
` 38D1A3EADDBEA9C` instead of
`038D1A3EADDBEA9C`
When using the `IssuerFingerprint` slice `%X` is enough but I changed it
to `%016X` too to be consistent.

Conflicts:
- models/asymkey/gpg_key_commit_verification.go
Ported the change to models/asymkey/gpg_key_object_verification.go
This is, in large part, a refactoring: we rename `CommitVerification` to
`ObjectVerification`, and adjust `ParseObjectWithSignature` (previously
`ParseCommitWithSignature`) to work on an object, rather than a commit.
This in turn, lets us implement `ParseTagWithSignature` on top of it, so
commit & tag signature verification will share most of the code.
