Cleanup av1_get_compressed_data()

In preparation for moving much of av1_get_compressed_data() to
av1_encode_strategy() I am performing refactoring and trying to reduce
its length.

* Move buf_8bit_valid clearing to assign_cur_frame_new_fb()
* Move aom_clear_system_state() to adjust_frame_rate() where it is
  required
* Make the fact that show_existing_frame only works in pass2 explicit
* Clear cm->show_existing_frame if show_existing_frame is disallowed
* Combine redundant *size = 0;

This forms part of wider restructuring and refactoring in order to
achieve a clean API separation at the entry to the low-level encoder.
