MapLibre Android 11.5.0 API incompatibility icon padding

[louwers]

Looks like MapLibre Android 11.5.0 introduces a backwards-incompatible when support for an array for icon-padding was merged #2845. Apologies for this, it was an oversight on my part, we aim to stick to strict semantic versioning.

The incompatible APIs are:

• SymbolLayer.getIconPadding() now returns a Float[] instead of a Float.
• PropertyFactory.iconPadding(padding) now requires a Float[] instead of a Float as parameter.

I can either revert the change in a patch release (technically making another breaking release), or let users migrate to the new API using the migration guide below.

Migration Guide

• Replace SymbolLayer.getIconPadding() with SymbolLayer.getIconPadding()[0].
• Replace PropertyFactory.iconPadding(value) with PropertyFactory.iconPadding(new Float[]{value}).

Opened #2880 to add PropertyFactory.iconPadding(Float) back.
