TagCommand: support signing annotated tags

Add the two config constants from C git that can switch on signing
of annotated tags. Add them to the GpgConfig, and implement actually
signing a tag in TagCommand.

The interactions between command line options for "git tag" and config
options is a bit murky in C git. There are two config settings for it:

* tag.gpgSign is the main option, if set to true, it kicks in if
  neither -s nor -u are given on the command line.
* tag.forceSignAnnotated signs only tags created via "git tag -m",
  but only if command-line option "-a" is not present. It applies
  even if tag.gpgSign is set explicitly to false.

Giving -s or -u on the command line also forces an annotated tag
since lightweight tags cannot be signed.
