Replace the texture-shaped RGB24 output with a linear raw buffer and
keep its packing, damage translation, and buffer copies inside the
RGB24 effect.
Benchmark full-frame native and packed processing and retain the faster
path for each source format. Preserve logical damage rectangles for
client updates and alternating framebuffer repair.
Return compute outputs to COMMON for COPY queue handoff and refresh
cached framebuffer sizes when switching packed and native layouts.
Handle DEFAULT, NEW, and UNCHANGED IDDCX HDR10 metadata states and
publish valid mastering metadata through KVMFR. Preserve the metadata
across post-processing without reallocating resources for
metadata-only changes.
