- Bump up macosxDeploymentTarget to 11 as lower is not supported anymore by latest macos release
- Cache docker build images in ghcr.io to speed up CI
…e by latest macos release Motivation: We need to bump up the target to be able to compile on latest macos release Modifications: Use 11 Result: Be able to compile again
Motivation: Every docker compose build in ci-build.yml, ci-pr.yml, ci-deploy.yml and ci-release.yml rebuilds the CentOS6/CentOS7-aarch64/Debian7/AL2023 images from scratch on each run since GitHub-hosted runners are ephemeral and have no persistent layer cache. ci-build.yml/ci-pr.yml previously worked around this with a type=gha buildx cache scoped per matrix leg; ci-deploy.yml and ci-release.yml had no docker layer caching at all. Modifications: Switch to buildx with a registry cache backend (ghcr.io) so the expensive image layers (devtoolset, OpenSSL built from source, cross-compile toolchains) are reused across runs and across workflows. Cache images are pushed to ghcr.io/netty/netty-tcnative-build-cache, distinct from netty/netty's own ghcr.io/netty/netty-build-cache, so the two repositories' caches can never collide or overwrite each other. Result: Speed up CI builds.
