Tool System: make smooth & randomize modal operators

Previously these used a gizmo to redo the operator however this
complicated having on-screen gizmos to access tools (see T66304).

Replace this with a generic way to make an operator that only has an
execute function into a modal operator.

This is used for smooth and randomize tools.

Unlike operator gestures, this handles storing and resetting the data.

Currently this only handles edit-mode data, however it's can be
extended to other kinds of data.
