Fixes #14401 which has been a bug in the 8.22.x and 8.23.x releases. When I removed the multiple initialisation of Matplotlib backends in #14330 it broke use of the following: ```bash ipython --matplotlib ipython --matplotlib=auto ipython --pylab ipython --pylab=auto ``` by failing to display Matplotlib plot. If you specify a particular GUI event loop such as using ```bash ipython --pylab=qt ``` then it was and is fine. So for anyone finding this, the workaround until the next release is to specify a GUI loop rather than relying on the auto selection. I didn't notice this as I've been concentrating on moving the Matplotlib backend logic from IPython to Matplotlib, and with those changes (matplotlib/matplotlib#27948) the above use cases all work OK. The fix is to reintroduce the early import of `matplotlib-inline` but only if both the gui loop is not specified and the Matplotlib version is before the movement of the backend logic across to it. There are no explicit tests for this. In the future I will try to think of some tests for some of this IPython-Matplotlib functionality that don't involve installing complicated backend dependencies or adding image comparison tests.

Possible fix for #14329.
With this change, the reproducers from the issue become:
and
It is still possible to call
matplotlib.pyplot.switch_backendtwice but only if you request%matplotlib inline, and theswitch_backendis called with same correct backend twice. This isn't ideal but it doesn't cause any problems apart from being a little slower than necessary.
