3f6cbeb87e LibGfx+LibWeb: Use mipmaps for downscaling images
This changes Gfx::ScalingMode to reflect the three modes of scaling we
support using Skia, which makes it a bit easier to reason about the mode
to select. New is ::BilinearMipmap, which uses linear interpolation
between mipmap levels to produce higher quality downscaled images.

The cubic resampling options Mitchell and its sibling CatmullRom both
produced weird artifacts or resulted in a worse quality than
BilinearMipmap when downscaling. We might not have been using these
correctly, but the new ::BilinearMipmap method seems to mirror what
Chrome uses for downscaled images.

59a867d3e3 Tests: Enable all screenshot tests on all platforms
With the newly supported fuzzy matching in our test-web runner, we can
now define the expected maximum color channel and pixel count errors per
failing test and set a baseline they should not exceed.

The figures I added to these tests all come from my macOS M4 machine.
Most discrepancies seem to come from color calculations being slightly
off.

b7efb61fbe Tests/LibWeb: Restructure Ref and Screenshot test dirs to match others
Now each test type has the same directories:
- input
- expected
- data

Also, tests can be in subdirectories within ./input.
