Move Rename branch from repo settings page to the page of branches list (#24380)

Co-Author: @wxiaoguang

It is more convenient that user just need to enter a new branch name after he selects the branch which he want to rename.
So this PR move the function of renaming branch to the page of branches list.

This PR also restyle the button of `new branch`, `download`, `delete`....
