Improve template helper (#24417)
It seems that we really need the "context function" soon. So we should clean up the helper functions first. Major changes: * Improve StringUtils and add JsonUtils * Remove one-time-use helper functions like CompareLink * Move other code (no change) to util_avatar/util_render/util_misc (no need to propose changes for them) I have tested the changed templates:     --------- Co-authored-by: Giteabot <teabot@gitea.io>pull/24409/head^2
