Subject: encode_api_test: add ConfigResizeChangeThreadCount
Origin: https://github.com/webmproject/libvpx/commit/af6dedd715f4307669366944cca6e0417b290282
Bug-Debian: https://bugs.debian.org/1053182
Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2023-5217
Update thread counts and resolution to ensure allocations are updated
correctly. VP8 is disabled to avoid a crash.
Bug: chromium:1486441
Change-Id: Ie89776d9818d27dc351eff298a44c699e850761b
