Align variance-based partition thresholds and force split logic with AV2's exponential quantizer scale for low resolutions (<= 288p). 1. Update qindex_low_thr and qindex_high_thr in tune_thresh_based_on_resolution() to 70 and 95, mapping AV1's linear QP scale to AV2's exponential QP scale. 2. Align the <= 360p 32x32 partition condition by removing the unguarded sub-variance condition that forced all 32x32 blocks to split. This allows 32x32 partition blocks to be properly selected on low resolution sequences in RTC mode, improving encoding speed. STATS_CHANGED for RTC mode
