tdf#89866 tdf#96504 vcl: fix printing of form controls with images

Originally in 2004 commit 0339e43208cd7b98d302e420b39ac32911acaa56 added a
"DBG_ASSERT( GetOutDevType() != OUTDEV_PRINTER, "DrawImage(): Images can't
 be drawn on any mprinter" );"

Recently commit f749ffbdf4c007f1a42bcafc9c2723c47bac22d1 made the mistake
of trusting this assertion to be correct and added Printer::DrawImage()
overrides that do a hard "assert()" now and don't do any drawing.

Armin claims that the implementation of OutputDevice::DrawImage() should
actually work for Printer as well due to fall-backs and thus the
original DBG_ASSERT was misleading.

This matters when printing documents that contain form controls
such as ImageControl.

Additionally, Image::Draw() should not return early when
IsDeviceOutputNecessary() is false, because that is the case when
printing, where instead a meta-file is recorded.
The called OutputDevice::DrawBitmapEx() will check
IsDeviceOutputNecessary() internally anyway.

This check was actually always there, so i do not understand how this
should have worked in LO 4.2, as the bug reporters claim.
