Add dmypy status file setting

[joecox]

Hello! When developing, I like to use mypy 2 ways:

• A mypy VSCode extension such as this one to see problems inline in my editor
• Run mypy as a pre-commit hook to ensure type errors are not committed

When using preferDaemon, I find that I cannot easily have both share the same daemon process.

• the extension generates a /tmp/.vscode.dmypy_status/status-<uuid>.json status file
• I can set --status-file in my pre-commit hook, but I can't know which file the extension is using

The impact of this is that running the pre-commit hook is slow as it cannot make use of the already running daemon.

I have also tried setting path to:

    "mypy-type-checker.path": [
      "${workspaceFolder}/.venv/bin/python",
      "-m",
      "mypy.dmypy",
      "--status-file",
      ".dmypy.json"
    ]

but the extension overrides that CLI option with its own.

Proposal

Add an optional daemonStatusFile setting which vscode-mypy uses as the status file.
