Update code guarded by bubble anything flag to use the helper method

Also adds a dependency on shared shell lib so launcher can use this.

Flag: com.android.wm.shell.enable_create_any_bubble
Test: manual - enable the create flag and check that bubble anything still
               works; same with bubble anything flag
