Optimize Docker layer caching to significantly reduce rebuild time when only source code changes: - Separate dependency installation from source code copy - Build brotli in build stage instead of runtime stage - Copy only dependency-related files before running make deps Signed-off-by: Sihyeon Jang <sihyeon.jang@navercorp.com>

Is there a significant change in the size of the image?

Please note the handling of the lib64 directory in the original install-brotli.sh script. https://github.com/apache/apisix/blob/master/docker/debian-dev/install-brotli.sh#L28-L32

Description
Optimize the debian-dev Dockerfile to leverage Docker layer caching more effectively.
Previously, any code change would invalidate the cache and trigger a full rebuild including
make depsand brotli compilation.What this PR does:
Separate dependency files from source code: Copy only
Makefile,rockspec,.requirements, andinstall-dependencies.shbefore runningmake deps, so dependencies are cached unless these files change.Move brotli build to build stage: Previously, brotli was built in the runtime stage, requiring installation of ~80 build packages (gcc, cmake, etc.) every time. Now it's built once in the build stage and only the binary is copied to runtime.
