Reference issue (if any)

As a part of Create a dipole fitting GUI that is better than XFit, this PR aims to fix #11892

What does this implement/fix?

Change view(to select only mags, grads, joining grads) and increase or decrease ylim using keyboard buttons only.

Currently behaves like this:

TODO:

  • Add tests in mne/viz/tests/test_topo.py
  • Improve consistency(reduce redundancy).
  • ylim ui button highlights on keypress.
  • Fix failures.

Additional information

Note: I have not used my mouse, though that is completely working too - by clicking on the UI buttons.
