[Skia] ASSERTION FAILED: bitmap->size() == updateSize :
BackingStore::incorporateUpdate(UpdateInfo &&) on a fractional device scale
factor display
https://bugs.webkit.org/show_bug.cgi?id=285718
Reviewed by Don Olmstead.
Windows supports fractional device scale factors. For example, 125%,
150% and 175% DPI display. BackingStore::incorporateUpdate has an
assertion that checkes a ShareableBitmap size is the bounding rect
size scaled by the device scale factor. However, this assertion failed
if the device scale factor was fractional.
<https://commits.webkit.org/279794@main> added `expandedIntSize` to
BackingStoreCairo.cpp to solve a same problem. Did the same for
BackingStoreSkia.cpp.
