Anim Picker: Remove dead __USE_OPENGL__ code path fixes #580

Following PR #609 which switched to unconditional QPainter.Antialiasing,
the __USE_OPENGL__ platform flag in anim_picker/widgets/basic.py and its
commented-out viewport block in anim_picker/gui.py were no longer read.
Drop them along with the now-unused platform and versions imports.
