Add logging functionality and Maven publishing setup

Added Logger class with various log levels to `commonMain`. Integrated `maven-publish` and `signing` plugins in `build.gradle.kts` to facilitate publishing artifacts to the Maven repository with proper credentials and metadata. Removed `gradle.properties` and updated `.gitignore` accordingly.
