Updated TaskDescription to pass drawable resource ID (1/2)

Depreciated the TaskDescription constructor when passing a bitmap and
added constructors to support passing drawable resource ID. Passing
drawable IDs allow users to use drawables such as AdaptiveIcons
instead of creating and passing a bitmap. Later SystemUI checks for
either bitmap, file name or resource ID to get a drawable to display.

Test: run-test CtsActivityManagerDeviceTestCases android.server.am
.TaskDescriptionTest
