Bug 2005490 [wpt PR 56680] - Compute gradient values in image-set(), a=testonly

Automatic update from web-platform-tests
Compute gradient values in image-set()

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

This CL implements resolution in CSSImageSetValue.
