WebP/Lossy: Add test for lossy webp with uncompressed alpha
The alpha channel of a lossy webp is always stored separately from
the (lossy) RGB data. Alpha is either compressed in a lossless webp
that stores just the alpha data, or it's stored completely
uncompressed. (But again, even if it's compressed, it's losslessly
compressed.)
This adds a test for uncompressed alpha, which I hadn't tested before.
It seems to work correctly, though :^)
I generated the test image by running:
~/Downloads/libwebp-1.3.0-mac-arm64/bin/cwebp \
-alpha_method 0 \
Tests/LibGfx/test-inputs/extended-lossless.webp \
-o Tests/LibGfx/test-inputs/extended-lossy-uncompressed-alpha.webp
