Set the bounds of the kdims List parameter

[maximlt]

I just ran the unit test suite of HoloViews with Param installed from holoviz/param#605 and a few tests failed. They failed when kdims List is overridden in a sub Parameterized class, and the overriding List is not defining explicitly the new bounds. In the current state of Param (1.x) , bounds is not inherited from any super class but is always the default of (0, None) (meaning a list of any length). With the tested PR bounds is inherited.

The change made in this PR was to set explicitly the bounds in the subclasses. Alternatively, one could have loosen bounds in the super classes. The commits list what change was made and why. For instance, one could have set bounds of Chart.kdims (super class) to (0, None) instead of updating bounds on Spikes.kdims (sub class) to (0, None). I didn't spend much time thinking about doing the alternative

I noticed there are a few typos in the commits, here are the changes made:

• set bounds to (0,None) to Spikes.vdims to override Chart.vdims bounds of (1, None)
• set bounds to (3,3) to Path3D.vdims to override Geometry.vdims bounds of (2, 2)
• set bounds to (3,3) to Scatter3D.vdims to override Geometry.vdims bounds of (2, 2)
• set bounds to (3,3) to TriSurface.vdims to override Geometry.vdims bounds of (2, 2)

@hoxbro this could be merged safely, and need to be merged not to break HoloViews with Param 2.0.
