If an intermediate tree already exists and we know this ahead of time,
we should use it without recreating it with all of its contents resolved
and written recursively. This commit adds support for such cases and
renames TreeBuilder's APIs to generalize away from accepting blob IDs
only.

Also addresses some required changes to tests hitting GetMergeTree via older
Git versions. This is because we use checkout to compute merge tree in those
cases, and we need to ensure that in the test, the worktree modified is that of
the temporary repository rather than the gittuf repository itself.

- Make CreateCommitObject support merge commits, with multiple parent
hashes
- Changed other files to use an array of parent hashes instead of a
single hash
- By changing the parameters for CreateCommitObject, internal/common had
errors that had to be fixed.

This allows us to perform additional checks in future such as whether an
object is replaced by a replace ref. It also makes it easier to switch
between go-git and another mechanism to invoke Git, such as directly
using the binary.

This removes the sub-go.mod in favor of updating all references to the
third_party/go-git package.
This lets users `go install` from outside of the module.
