ANDROID: add vendor hooks for getting information of dtask

Add new hooks for debugging for disksleep tasks.

It helps the bootloader and the panic handler produce debugging
information about what the tasks are waiting for. It can be obtained
through Ramdump or kernel log, and this information can be used to
quickly classify and respond to problems.
