Rename ImageBuffer.logicalSize to ImageBuffer.truncatedLogicalSize
https://bugs.webkit.org/show_bug.cgi?id=232515
<rdar://problem/84829689>

Reviewed by Tim Horton.

Source/WebCore:

This is a purely mechanical change, and is the first step in
https://bugs.webkit.org/show_bug.cgi?id=225377. Once we have both logicalSize()
and truncatedLogicalSize(), we can start migrating callers to the correct one
and away from the trucated one.

I did this rename by adding truncatedImageSize, and then temporarily renaming
logicalSize() to some dummy value - to force compilation failures at every call
to logicalSize(). Then, once compiling found all the call sites, I renamed it
back to just logicalSize().

No new tests because there is no behavior change.
