Migrate to Compose Resources or MoKo Resources

[jacobras]

Issues with Libres:

• cannot set package visibility (Generated Res class in root package makes IDE autocomplete/import difficult #92)
• cannot change generated package (Generated Res class in root package makes IDE autocomplete/import difficult #92)
• doesn't support watchOS (WatchOS target #60)
• doesn't support setting region ([Feedback wanted] Distances: auto-conversion #142)

Compose Resources should be a closer-to-the-ecosystem replacement. However, it's lacking:

• manually setting locale (https://youtrack.jetbrains.com/issue/CMP-4197)

MoKo Resources:

• can set package visibility
• can change generated package
• supports watchOS
• supports setting a region
