When there are 2 negative lookaheads in the same rule, let's say `!"(" blabla "," !")"`, there will the 2 `FunctionCall`'s where assigned value is None. Currently when the `add_var` is called
the first one will be ignored but when the second lookahead's var is sent to dedupe it
will be returned as `None_1` and this won't be ignored by the declaration generator in the `visit_Alt`. This patch adds an explicit check to `add_var` to distinguish whether if there is a variable or not.

Allows contextvars from the main thread to be accessed in the separate thread used in `asyncio.to_thread()`. See the [discussion](#20143 (comment)) in GH-20143 for context.

Without this, only the _zoneinfo module is getting installed, not the
zoneinfo module. I believe this was not noticed earlier because
test.test_zoneinfo was also not being installed.

This allows building with older versions of the Windows SDK where the value is not defined.

Use text/x-python instead of text/plain to avoid issues with tools assuming that "ShellExecute(script)" is a non-executable operation.

Implements `asyncio.to_thread`, a coroutine for asynchronously running IO-bound functions in a separate thread without blocking the event loop. See the discussion starting from [here](#18410 (comment)) in GH-18410 for context.
