Bug 2005478 [wpt PR 56678] - Compute gradient values in cross-fade(), a=testonly

Automatic update from web-platform-tests
Compute gradient values in cross-fade()

Top level gradient values had values computed as necessary,
but not as gradients inside image-set() and cross-fade().

This CL implements resolution in CSSCrossfadeValue. CSSImageSetValue
resolution will be done in another CL.
