Use class.qualifiedName instead of class.simpleName in wasmJsMain where applicable (JetBrains#2780)

Since we migrated to Kotlin 2.3.0 we can use `class.qualifiedName` in
k/wasm out of a box.

Before that, we used to use `class.simpleName`. I changed it in our
modules where it makes sense.
Additional changes will be made in other modules published from androidx
