[IMPROVEMENT] Refactor and optimize Dockerfile (#1696)

* [FIX] Corrected bitness check for 64-bit systems

* Improve Dockerfile: cleanup, parallel build, and remove redundancies
- Replaced cd with WORKDIR for clarity and Docker best practices.
- Removed unused LIB_CLANG_PATH export, as it only affected a single build layer; the library is automatically detected during build.
- Parallelized the GPAC build using make -j$(nproc).
- Removed redundant CMD instruction, as ENTRYPOINT already defines the container's execution command.

* [DOCS] Update CHANGES.TXT for Dockerfile improvements
