Leon Scroggins III 194580dc60 Reland "Treat kWEBP encode with quality=100 as lossless" 
This reverts commit 22170b3178.

It was reverted due to the test breaking Google3. This includes a
workaround.

    Original change's description:
    > Treat kWEBP encode with quality=100 as lossless
    >
    > In SkEncodeImage and friends, treat quality of 100 as a lossless encode
    > when using kWEBP. This seems a good fit for the intent - which is
    > presumably to save the highest quality image. This also matches
    > Chromium's blink::ImageEncoder::ComputeWebpOptions, which treats a
    > quality of 1 (on a float scale from 0 to 1) as a lossless encode.
    >
    > FWIW, Chromium has had this behavior since
    > https://codereview.chromium.org/1937433002, in response to
    > crbug.com/523098. The goal is to "maintain sharpness to
    > match the JPEG encoder behavior (use WEBP lossless encoding)".
    >
    > Add a test to verify the new behavior. This requires making tests
    > depend on libwebp to use WebPGetFeatures, since the Skia API does not
    > provide a way to determine whether an encoded webp file was encoded
    > lossless-ly or lossily.
