8d4c5baf - Make local mirror of cmake dependencies configurable (#26042)

Make local mirror of cmake dependencies configurable (#26042) ### Description <!-- Describe your changes. --> - Added support for the `--cmake_deps_mirror_dir` option to allow users to specify a custom local directory for CMake dependencies. - Improved logging to show the source of `FetchContent` in CMake. ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> - Previously, ONNX Runtime searched for CMake dependencies only in the default `<repo_root>/mirror` directory. - This change enables users to configure an alternative location for storing CMake dependencies, offering greater flexibility in build environments.
