Cleanup Gradle dependencies and miscellaneous improvements

[SimonMarquis]

• ~Inline versions that were used only once, allowing us to use the compact form for libraries & plugins~
• Merge TOML declarations with group + name into the unique module component
• Expose new BoMs to enforce versioning across packages (coil-kt-bom, kotlin-bom, kotlinx-coroutines-bom, kotlinx-serialization-bom, protobuf-bom, okhttp-bom, retrofit-bom)
• Refactor jacoco version declaration into a proper dependency declaration to enable actual dependency tracking
• Rename androidx.hilt.navigation.compose to hilt.ext.navigation.compose to match the already existing hiltExt group.
• Replace duplicated *.gradlePlugin dependencies with converter that converts plugin alias to usable dependencies.
• Sort dependencies
• Remove unused kotlinx-coroutines-android dependency
