and use it to suppress a false positive related to data that passes
through RGBA32PackedToPlanar_16b_SSE41(). Current versions (tested with
clang 13.0.1, using -O0 and the build from oss-fuzz of enc_dec_fuzzer)
model shuffles incorrectly reporting use of uninitialized
data related to the alpha change that's removed when converting to YUV.
valgrind behaves correctly, however.

libwebp still has a size threshold of 4 pixels in picture_csp_enc.c
but the sharpyuv library itself can handle any image size.

- Remove SHALF constant so that we get back the original value when
calling UpScale then downscale with rounding
- Make the linear->gamma precomputed table bigger (8 bits rather than 5)
- Round values in kLinearToGammaTabS

The forward transform subtracts the deltas, the inverse adds them.

Remove unused constants.
Use ALL_CAPS for defines and kCamelCase for static const values.
Change some defines into static constants if they are not used in array sizes.
