sci-libs/opencascade: use single slot/subslot for 7.5.3

Instead of using different slots for different versions, the package now
uses a single slot with subslots. This is to simplyfy dependency handling
in revdeps.

Allow build against sci-libs/vtk-9.1.0

-#   if set to 1, the memory manager performs it's own internal optimization.
-#      Will be set, if the 'optimize' USE flag is set.
