This patch adds a `scripting extension generate <ExtensionType>...`
command that introspects a Python extension base class and emits a
skeleton subclass with `# TODO: Implement` stubs for its abstract
methods (or, with `-a`, every method), then opens the result in an
editor.
Generated imports use `from <module> import <class>`, and the generated
`__init__` forwards its arguments to `super().__init__(...)` since every
base class relies on its constructor to set up attributes
(`self.target`, `self.process`, ...) that inherited, non-overridden
methods depend on. When the host can't open an external editor (e.g.
non-macOS), the command reports that as a message rather than an error,
since the file is already written.
To catch regressions in the generator itself instead of just checking
that a file was produced, this patch adds
`TestScriptingExtensionGenerate.py`, which generates a template for
every extension kind on the fly and drives it through a live lldb
session (`process launch -C`, `breakpoint set -P`, `target stop-hook add
-P`, etc.).
