Revert "Revert "tdf#118133 DOCX import: disable lazy-loading of tiff images""
This reverts commit c6bf16909d.
Lazy-loading doesn't work with cropped TIFF images, because in case of Lazy-load TIFF images
we are using MapUnit::MapPixel, but in case of cropped images we are using MapUnit::Map100thMM
and the crop values are relative to original bitmap size.
