Add a command to perform automatic data collection for bug reporting

A command could be added to collect the following:

• Contents of current configuration in c_cpp_properties.json
• Output of the Log Diagnostics command
• All C_cpp related settings (or all VS Code settings?)
• Contents of C/C++ output channel (may require preserving what is output to it, if it's not readable).
• others?

.. and provide guidence on providing that information by opening an issue on github.

Guidance on github could refer users to running this command and including that information when opening an issue.

まず、要求されたデータソースを確認します: c_cpp_properties.json、Log Diagnostics コマンド、C/C++ 設定、C/C++ 出力チャネル。コマンドの範囲、出力をどのように保持すべきか、どの追加データが必要か、そして GitHub issue の案内でユーザーをどのように誘導すべきかを明確にします。要件と収集フローについて合意できれば完了です。
