SVGHMI: remove intermediate "updates" Map and apply_updates()

It was used initially to decouple DOM updates from reception of data through
websocket, but now since all widget SHOULD use animate() to modify DOM, and
dispatch() only change internal state, apply_update is unnecessary.
// widget_tooglebutton.ysl2
widget_desc("ToggleButton") {
longdesc
||
Button widget takes one boolean variable path, and reflect current true
or false value by showing "active" or "inactive" labeled element
respectively. Clicking or touching button toggles variable.
||
shortdesc > Toggle button reflecting given boolean variable
path name="value" accepts="HMI_BOOL" > Boolean variable
}
widget_class("ToggleButton") {

frequency = 5;
active_style = undefined;
inactive_style = undefined;
dispatch(value) {
this.activity_state = Boolean(value);
//redraw toggle button
this.request_animate();
}
on_click(evt) {
//toggle state and apply
this.activity_state = this.activity_state ? false : true;
this.apply_hmi_value(0, this.activity_state);
//redraw toggle button
this.request_animate();
}
init() {
this.element.onclick = (evt) => this.on_click(evt);
this.activity_state = undefined;
}

widget_defs("ToggleButton") {
activable();
