ANDROID: GKI: use public type definitions in vendor hooks

This change is intended to reduce the chance of a missed ABI break
involving vendor hooks.

The following type is now fully defined in ABI XML.

* `struct timekeeper`

symbol '__traceiter_android_rvh_account_irq' changed
  CRC changed from 0x18e0dccf to 0x4e82c102

symbol '__traceiter_android_rvh_after_dequeue_task' changed
  CRC changed from 0x7efc419b to 0x1c0066e1

symbol '__traceiter_android_rvh_after_enqueue_task' changed
  CRC changed from 0xd6f0f603 to 0xf7eaafb8

... 75 omitted; 78 symbols have only CRC changes
