Include SysUIUnfoldComponent only in phone SystemUI

Change Dagger depepdencies structure to add
SysUIUnfoldComponent subcomponent only
in phone SystemUI modules.

- SystemUIModule is included in all variants of
  SystemUI (e.g. for TV/Chromium/tablets/etc.)
- CommonSystemUIUnfoldModule binds optional of
  Optional<SysUIUnfoldComponent>, so this dependency
  will be present only if the component of this specific
  variant has this dependency.
- CommonSystemUIUnfoldModule is part of SystemUIModule,
  so it is also added in all variants of SystemUI.
  It doesn't actually contain the dependency, it's just
  a proxy module to unwrap optional dependency
  from SysUIUnfoldComponent
- SysUIUnfoldComponent is provided by SysUIUnfoldModule,
  SysUIUnfoldModule is only added in the variants where
  unfold classes might be useful (e.g. phone variant
  of SystemUI), so this dependency will be present
  only in these variants of SystemUI
