Revert "ecore-evas reduce modifier modification on every event to cut cpu"

This reverts commit 3a9d54085b8751cbd0bca4698a8ff702d9bdc7b4.

I got crash and a lot of valgrind warning with this patch. All in all, I
think we can just wait for next release and do a proper cleanup of our API
to not rely on strings at all.

For references this is the first valgrind warning I get (Not going to past the 100 following one) :
