Frameworks: add all slim shortcut image resources

Importing for now the old one from KitKat. Graphics group is currently
vectorizing and revamping all. When they are finished we overwrite them and
add xxxhdpi ones as well.

Doing this now due that it is stopping the progress on a bunch of features right now

And a small method renaming to be inline with the other methods

Add missing file

core/java/com/android/internal/util/crdroid/ActionHelper.java
Frameworks: icon materialization

These are the first few. There are still 23 more shortcut image
        resources that need to be done, and these will come
        sometime next week probably.
