Improve build efficiency by preventing duplicate merges

Introduced a private property to the `NccCompiler` class, `$merged_dependencies`, to keep track of the dependencies that have already been merged. This prevents unnecessary re-merging during the build operation, potentially enhancing the efficiency of the process. The implementation involves a check for a preexisting merge before a new merge is performed. If a merge already exists, the process is skipped, thereby avoiding redundancies.
