Add FPDF_PRINTMODE_EMF_IMAGE_MASKS print mode.

This is a new Windows-only print mode for use with FPDF_SetPrintMode().
It outputs EMF, like FPDF_PRINTMODE_EMF, but can process image masks
more efficiently under certain conditions.

By adding this additional print mode, embedders can choose whether to
use it at run time. This in turn allows embedders to roll out this
improvement, which has been known to cause regressions in the past, in a
controlled manner.
