Implement UserCherryPick in Go

This implements the `UserCherryPick` command in Go. It uses
`gitaly-git2go` to call `func (*Repository) Cherrypick`.

This feature is behind a feature flag and is disabled by default. The
Ruby implementation is kept (for now) and is the default.

The feature flag roll-out issue:
https://gitlab.com/gitlab-org/gitaly/-/issues/3281

Closes: https://gitlab.com/gitlab-org/gitaly/-/issues/3071
