Using kwargs with `typing.NamedTuple` not recognized

[rkoeninger]

This is being reported in response to an issue with pylint: pylint-dev/pylint#4431

This issue may also be related to:
See #109
See #421

Steps to reproduce

1. Declare a named tuple using kwargs syntax: Point = NamedTuple("Point", x=float, y=float)
2. Try to create an instance of this type: p = Point(1, 2)

The kwargs behavior is noted since 3.5 in the source code for CPython here:

https://github.com/python/cpython/blob/3.5/Lib/typing.py#L2176-L2213

Current behavior

astroid will not identify Point as callable.

This causes pylint to report a not-callable error for the application of Point.

Expected behavior

The Point type from the Steps to reproduce should be identified as a callable object.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

2.8.5

Visible in current version:

https://github.com/PyCQA/astroid/blob/b07eb62466ae54bb0209d9253b7018a5d4c764e2/astroid/brain/brain_namedtuple_enum.py#L521-L522

The number of expected node.args is exactly 2 - one for the name of the named tuple type and one for the list of members. This line will probably have to be replaced with something like len(node.args) >= 2 or further examine ast for list of tuples vs kwargs syntax.
