Fix doubled control application (#7550)

With reactivity fixed, control widgets would apply twice. This is fixed
by using the litegraph implementation.

Also adds control widget support for combos

Followup to #7539.

Known Issue:
- Primitive node do not have litegraph callbacks properly setup. As a
result, they will display an updated value when modified by control
widgets. Fixing this will requires a larger, separate PR
