Add stability configuration file for maps-compose-utils module

[bubenheimer]

android-maps-compose 4.3.4

The maps-compose-utils module should use a Compose stability configuration file to potentially improve recomposition performance, just like the primary maps-compose module. See #152, #517.

These 2 modules could share a single stability configuration file containing all immutable types from the GoogleMap SDK model package that are used in the modules.

For immutable types this is expected to be more performant than relying on the upcoming strong skipping functionality in Compose 1.7.0, which is more appropriate for mutable types.
