Use frontend fetch for branch dropdown component (#25719)
- Send request to get branch/tag list, use loading icon when waiting for response. - Only fetch when the first time branch/tag list shows. - For backend, removed assignment to `ctx.Data["Branches"]` and `ctx.Data["Tags"]` from `context/repo.go` and passed these data wherever needed. - Changed some `v-if` to `v-show` and used native `svg` as mentioned in https://github.com/go-gitea/gitea/pull/25719#issuecomment-1631712757 to improve perfomance when there are a lot of branches. - Places Used the dropdown component: Repo Home Page <img width="1429" alt="Screen Shot 2023-07-06 at 12 17 51" src="https://github.com/go-gitea/gitea/assets/17645053/6accc7b6-8d37-4e88-ae1a-bd2b3b927ea0"> Commits Page <img width="1431" alt="Screen Shot 2023-07-06 at 12 18 34" src="https://github.com/go-gitea/gitea/assets/17645053/2d0bf306-d1e2-45a8-a784-bc424879f537"> Specific commit -> operations -> cherry-pick <img width="758" alt="Screen Shot 2023-07-06 at 12 23 28" src="https://github.com/go-gitea/gitea/assets/17645053/1e557948-3881-4e45-a625-8ef36d45ae2d"> Release Page <img width="1433" alt="Screen Shot 2023-07-06 at 12 25 05" src="https://github.com/go-gitea/gitea/assets/17645053/3ec82af1-15a4-4162-a50b-04a9502161bb"> - Demo https://github.com/go-gitea/gitea/assets/17645053/d45d266b-3eb0-465a-82f9-57f78dc5f9f3 - Note: UI of dropdown menu could be improved in another PR as it should apply to more dropdown menus.
