contrib: aom: update to 3.13.0

- New Features
    * New tuning mode AOM_TUNE_SSIMULACRA2 for the AOME_SET_TUNING codec
      control (--tune=ssimulacra2) in all-intra mode. The feature
      detection macro AOM_HAVE_TUNE_SSIMULACRA2, if defined, indicates
      that AOM_TUNE_SSIMULACRA2 is available. AOM_TUNE_SSIMULACRA2 was
      developed to maximize SSIMULACRA 2 scores.
    * New codec control AV1E_SET_SCREEN_CONTENT_DETECTION_MODE
      (--screen-detection-mode).
      This codec control helps select between two screen detection modes:
       * Mode 1: standard (default)
       * Mode 2: anti-aliased text and graphics aware
    * New codec control AV1E_SET_ENABLE_ADAPTIVE_SHARPNESS
      (--enable-adaptive-sharpness). When enabled, it modulates sharpness
      based on frame QP, which helps mitigate blocking artifacts in the
      low to medium quality range.
    * Added low complexity decode mode for 720p vertical videos.
    * ROI feature implemented for RTC: for delta QP, skip encoding, and
      reference selection.
    * External scaling feature for SVC: allow downscaled images to be
      passed into encoder for spatial layers without reconfiguring it.
    * Allow per-frame calculation of PSNR (contribution from Meta).

  - Compression Efficiency Improvements
    * Variance Boost is now enabled for tuning modes AOM_TUNE_IQ and
      AOM_TUNE_SSIMULACRA2 at speeds 8 and 9 (2-5% SSIMULACRA 2 BD-Rate
      gains)
    * Several quality/time tradeoff improvements and bug fixes for all
      intra mode speeds 8 and 9.
      * Up to 6.9% SSIMULACRA 2 BD-Rate gains for speed 8
      * Up to 2.2% SSIMULACRA 2 BD-Rate gains for speed 9

  - Perceptual Quality Improvements
    * RTC: Visual quality improvements for screen content mode.
    * RTC: Visual quality improvements for video mode for resolutions >=
      720p.

  - Speedups
    * Optimize intraBC search for better speed/efficiency tradeoffs for
      all intra mode speeds >= 1
    * Optimize intraBC block hashing process
    * RTC Screen: speed feature added to speed 12 for ~2x speedup on
      slide/scene changes, for resolutions >= 720p.
    * ML based speedup improvement on the partition pruning for speed <= 2

  - Other Improvements
    * Fixes for RPS (reference picture selection) for RTC: Based on
      av1_discuss issue:
      https://groups.google.com/a/aomedia.org/g/av1-discuss/c/sqFad980SsA

  - Bug Fixes
    * b:421196988: all intra speed 8: overuse of palette mode
      unnecessarily inflating file sizes
    * b:423804955: Improve quality for 4K Screencast
    * webrtc:388070060: Allow per-frame calculation of PSNR
    * b:433046392, b:432035817: Fix to SVC crash triggered with Jitsi
      video conference app.
    * b:419622699: Fix integer overflow in update_buffer_level
    * b:407813259: Fix to update seq_params for number of layers change
    * b:400885218: External scaling for AV1
    * b:391849810: High AV1 frame encode time on slide changes
    * b:399575647: Too aggressive QP backoff at scene changes
    * b:383306740: Quality degradation at horizontal scrolling
