plug-ins: add option to crop layers to image bounds when exporting TIFF

Browse Source 
In file-tiff, add an option to crop the layers to the image bounds
when exporting individual layers (using GIMP_EXPORT_NEEDS_CROP
added in the previous commit), since TIFF has no concept of global
image bounds otherwise.  Cropping is enabled by default.
