Add keymap (default: G) to toggle minor grid.
If either minor grid is on, turn both of them off. Otherwise, turn all major and minor grids on (it usually doesn't make sense to have the minor grids only). Also change the behavior of `keymap.grid` ("g") to synchronize the grid state of both axes. Otherwise, if starting from only grids in one direction (`plt.plot(); plt.grid(axis="x")`), "g" switches between only `x` grid and only `y` grid, which is unlikely to be the expected behavior.
