This adds accessors for WidgetsBinding.instance.focusManager and WidgetsBinding.instance.focusManager.primaryFocus so that they can be more easily found in IDEs and accessed.

This adds a top level getter for WidgetsBinding.instance.focusManager.primaryFocus called primaryFocus, and a static accessor FocusManager.instance that returns WidgetsBinding.instance.focusManager.

Makes sure that disabled InkWell/InkResponse and widgets that use them don't allow themselves to be focused.

ListTile, PopupMenu, and Stepper were not setting canRequestFocus properly on the InkWell, and InkWell was allowing focus even if it was disabled (it was basically just relying on the containing widget to set canRequestFocus properly). Now InkWell must both be enabled (have an onTap or similar) and have canRequestFocus set to true.

This reverts commit e091d724.
