Use SymbolManager and have icon sizes depending on the zoom

Hello,
I found myself needing to use SymbolManager to drag and drop, and I realized that you can't specify an expression.
This is a shame because the icons are fixed in size.
To solve my problem, I did the following:

```
class ScaleSymbolManager(mapView: MapView, maplibreMap: MapLibreMap, style: Style) : SymbolManager(
mapView, maplibreMap, style
) {
override fun setDataDrivenPropertyIsUsed(property: String) {
when (property) {
"icon-size" -> layer.setProperties(
iconSize(
interpolate(
linear(), zoom(),
stop(9, 0.0f),
stop(10, 1.0f),
stop(12, 1.5f),
)
)
)

"text-size" ->
layer.setProperties(
textSize(
interpolate(
linear(), zoom(),
stop(9, 0.0f),
stop(10, 10f),
stop(12, 14f),
)
)
)

else -> super.setDataDrivenPropertyIsUsed(property)
}
}
}
```

I don't think this is the right method but it works while waiting for a better answer.

Start with SymbolManager and its setDataDrivenPropertyIsUsed override, then inspect how MapView, MapLibreMap, and Style are wired into the manager. Done means icon-size and text-size can use zoom-dependent expressions without requiring a custom SymbolManager subclass, while preserving drag-and-drop behavior.
