Revert "Sculpt: Register sculpt brush op so it clears last operator panel"

This reverts commit 11bdc321a274712e5c5ae83ff2c199690f66ecf7.

This change caused T101743, in general OPTYPE_UNDO should not be used
to control the UI.

This also caused 2x undo pushes to be performed when sculpting,
although sculpt mode doesn't add a step for the second undo push
so it wasn't visible to the user.

An alternative fix will be applied separately as it's too risky this
close to a release.
