tooling: Migrate Pylance settings from VSCode to pyproject.toml.

Pylance ignores python.analysis.* in settings.json when a pyproject.toml
exists and warns "cannot be set when a pyproject.toml is being used".

Move typeCheckingMode, extraPaths, stubPath, and diagnosticSeverityOverrides
into [tool.pyright] in pyproject.toml where Pylance reads them. This also
makes the configuration IDE-agnostic (works for any pyright-based tool,
not just VSCode).
