gh-149117: Set `ImportError.name` on errors from `runpy.run_module`/`run_path` (gh-149159)

Set ImportError.name on errors from runpy.run_module/run_path

`runpy.run_module()` and `runpy.run_path()` now set the `name` attribute
of the `ImportError` they raise to the requested module name, matching
the behaviour of a regular import statement (previously `name` was
always `None`, which broke introspection).

The `name=` kwarg is gated on `issubclass(error, ImportError)` because
`_get_module_details()` is also used by `_run_module_as_main()` with
a private `_Error` sentinel class. `_Error` does not subclass
ImportError, and `BaseException.__init__` rejects unknown kwargs at
the C level, so passing `name=` unconditionally would break the
`python -m foo` codepath.
(cherry picked from commit ff35fe4633cc6d3a30f6af8281dfa641783c1d07)
