### Node resize overhaul
- Precisely calculates node minimum size
- Prevents input & output overlap
- Prevents (normal*) widgets from rendering text over the edge of nodes
- Performance impact was sub-millisecond for normal usage in a 500-node
graph
_Minimum size for a few example node configurations_
### Widgets
- Converts hard-coded draw render values to class static properties
- Adds widget button draw function for left/right arrow widgets
_*_ Exception: `control_after_generate`, as it is not a true input /
widget. A check may be added later to handle this special case.
This PR is the litegraph side change necessary for widget sockets
feature in ComfyUI_frontend. Changes include
- Add readonly `Widget.computedDisabled` property for getting the
computed disabled state. When the associated socket is connected, the
widget is disabled
- Dynamically show the associated socket when
- the mouse is over the widget
- the slot is valid during link drop
- the slot is connected
- Removes the legacy widget drop behavior
