Fix scale_factor bug and refactor BITRATE_ACCURACY

1) Make the usage of scale_factor follow the design. One scale
   factor per update_type.
   Before this change, we only use first frame's scale factor in
   the GOP as the scale factor for every frame in the GOP.
2) Several miscellaneous changes.
   a) Remove unused keyframe_bitrate
   b) Merge stats_valid into tpl_txfm_stats
   c) Update abs_coeff_mean after tpl_stats are computed
   d) Simplify the parameters of av1_q_mode_estimate_base_q
      Rename it to av1_vbr_rc_info_estimate_base_q
   e) Add unit test for av1_vbr_rc_set_gop_bit_budgeta()
   f) Write unit test for av1_vbr_rc_info_estimate_gop_bitrate
      Test scale_factors properly
