[chromium] Scroll deltas should be floats
https://bugs.webkit.org/show_bug.cgi?id=111465
Reviewed by James Robinson.
This converts the remaining scroll delta fields to floats so that
we no longer lose precision due to DIP conversion. The natural
type for deltas is WebFloatSize, which was missing, so I also created
that type based on the existing WebSize header.
