   swscale/x86/rgb_2_rgb: fix uyvytoyuv422 overwrite on odd width
   uyvytoyuv422 converts packed UYVY, whose macroblocks are pixel pairs, and
   the SIMD code only handled even widths. On an odd width the trailing half
   macroblock made the kernel write past the end of the Y/U/V destinations:
   the AVX512ICL masked tail dropped the odd pixel and the fall-through
   re-entered the SIMD loop, writing a full mmsize*2 chunk past the planes
   (127 bytes of Y, 63 of U and 63 of V); the sse2/avx/avx2 scalar tail
   wrote one byte past the Y plane.
   
   Process only whole pairs and emit the trailing odd column from a small
   per-row epilogue that matches uyvytoyuv422_c (ydst[w-1] = src[2w-1],
   udst[cw-1] = src[2w-2], vdst[cw-1] = src[2w]).
   
   All four SIMD variants are now bit-exact with the C reference for even and
   odd widths and no longer overwrite the destination. Verified on AVX512ICL
   hardware (Ryzen 9 9950X) with checkasm.

   swscale/aarch64: fix uyvy/yuyv to yuv420p/yuv422p on odd width
   interleaved_yuv_to_planar, shared by uyvytoyuv422, uyvytoyuv420,
   yuyvtoyuv422 and yuyvtoyuv420, only handled even widths. The packed
   UYVY/YUYV macroblocks are pixel pairs and the trailing half macroblock of
   an odd width was mishandled:
   
   - the slow path (width <= 31) decrements its pixel counter by two from an
     odd value, so it never reaches zero and the loop runs far past the line,
     overwriting the destination (observed as a crash in checkasm);
   - the fast path (width >= 32) shifts the tail pointers back by width-32 and
     reprocesses an overlapping, misaligned tuple, producing wrong samples and
     dropping the last chroma column.
   
   Process only whole pixel pairs and emit the trailing odd column from a
   per-line epilogue that matches the C reference: for yuv422 one Y, U and V
   sample; for yuv420 the Y of both lines of the pair with the chroma averaged
   across them, and luma only for the final line when the height is odd. The
   empty even part (width 0 or 1) is guarded so the slow path no longer enters
   its run-past loop.
   
   All four variants are now bit-exact with the C reference for even and odd
   widths. Verified with checkasm under qemu-aarch64.
