Subject: [PATCH] COMP: Remove unused InputPixelType aliases in
 CopyIterationBenchmark

CopyRegionIterator and CopyScanlineIterator declared InputPixelType
but never referenced it, triggering -Wunused-local-typedef. Other
methods (CopyMemcpy, CopyImageRegionRange) still use the alias where
it is needed and are left unchanged.
