Move some providers to prevent accidental injection of main-thread elements

- Each Choreographer instance is actually thread-local, and moving this
  to the SysUIConcurrencyModule also helps to ensure that WMShell
  components can't accidentally inject a non-ShellMainThread
  Choreographer instance
- Also remove the deprecated non-qualified Handler global provider for
  the same reason
