Up until now, I had been using --mount=type=cache to mount the ccache directory in the Dockerfile, but I found that when the layer cache of the Docker build cache is invalidated, ccache also ends up being empty.
Therefore, by mounting the host's ccache directory using --mount=type=bind, this PR can avoid the impact of the Docker build cache. This ccache directory is saved as a cache in GitHub Actions, allowing it to be reused in subsequent builds.
