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_switch.ysl2
widget_desc("ListSwitch") {
longdesc
||
ListSwitch widget displays one item of an HMI:List depending on value of
given variable. Main element of the widget must be a clone of the list or
of an item of that list.
Given variable's current value is compared to list items
label. For exemple if given variable type
is HMI_INT and value is 1, then item with label '1' will be displayed.
If matching variable of type HMI_STRING, then no quotes are needed.
For exemple, 'hello' match HMI_STRING 'hello'.
