[WP] Avoid calling IOSurfaceAlignProperty
https://bugs.webkit.org/show_bug.cgi?id=235659

Reviewed by Simon Fraser.

Source/WebCore:

Add information about alignment of bytes per row to IOSurface class.

* platform/graphics/cocoa/IOSurface.h:
* platform/graphics/cocoa/IOSurface.mm:
(WebCore::surfaceBytesPerRowAlignment):
(WebCore::IOSurface::bytesPerRowAlignment):
(WebCore::IOSurface::setBytesPerRowAlignment):

Source/WebKit:

Avoid calling IOSurfaceAlignProperty in the WebContent process, since it requires IOKit access.
Information about the alignment of bytes per row of IOSurface will be retrieved in the UI process,
and sent to the WebContent process, where it will be stored.
