more fixes for SfxItemState

In commit 88a874fc "convert SfxItemState constants to a proper enum"
I made some mistakes in converting bitwise logic to boolean logic.

I fixed one of those places in commit 7ad83656 "fix bitwise->logic
conversion in SfxItemState commit"

This commit fixes the other places where I converted bitwise to normal
boolean logic. I also validated that none of the existing code tries to
uses combinations of these enum values.

This commit also introduces an exception-throwing check in the one place
where the enum is explicitly cast to make sure that no combinations
sneak in.
