Move member/watch actions to "Members/Watchers" page

Summary:
Ref T10054. This tries to make the members page a bit more consistent and provide hints to users about subproject/milestone membership rules. In particular:

  - You now join, leave, watch, unwatch, add and remove members, and lock and unlock membership from the members screen.
  - We now explain the membership rule for the project on this screen. There are currently four rules:
    - Normal Project: Join/leave normally.
    - Parent Project: Uses subprojects to determine members.
    - Milestone: Uses parent project to determine members.
    - Locked: Membership is locked.
    - (Future) Imported from LDAP/other external sources: Membership is determined by something else.

Test Plan: {F1064878}
