Support splitting Compose Multiplatform Resources

**Is your feature request related to a problem? Please describe.**
Unnecessary native Android resources are stripped away based on density. It would be nice if that would also work for Compose Multiplatform Resources, which are stored in `/assets/drawable-[density]` folders.

Currently reported at https://youtrack.jetbrains.com/issue/CMP-8509/Compose-Multiplatform-Resources-Density-Split-not-supported but I wonder if it may be more suitable here.

**Describe the solution you'd like**
Unnecessary densities from `/assets` folder stripped away.

**Describe alternatives you've considered**
Not sure if there's any alternative as the bundle goes to the Play Console directly, and needs to have all densities on board.

**Additional context**
