When creating a ReflowInput for inner table frame in CreateReflowInputForInnerTable(), we pass the customize border & padding if the table frame is border-collapsed. Similarly, when creating a SizeComputationInput for inner table frame, we should be able to pass border & padding rather than having a specialized logic in SizeComputationInput::InitOffsets(). This patch makes this a reality. Differential Revision: https://phabricator.services.mozilla.com/D104350
