Build/Test Tools: Improve devcontainer setup for non-Codespaces usage

This now runs in local Docker as well. Sets the executable propset to explicitly identify `install-tool.sh` and `setup.sh` as executable. Unclear if this will sync via the Git mirror; ideally it would as otherwise the two files show as modified in a Git clone even in a fresh container.

Props samruddhikhandale.
See #57187.
