Holoviews: Allow position of legend to be set with coordinate tuple as in Bokeh

[rjp23]

Bokeh: https://bokeh.pydata.org/en/latest/docs/user_guide/styling.html#location

Legend positions can be set by position names but also by: a (x, y) tuple indicating an absolute location in screen coordinates (pixels from the bottom-left corner).

Holoviews supports the named-positions but not the coordinates.

Incidentally, I can't find out how to change the position of a legend (even with just the position name) anywhere in the Holoviews documentation. Legends could be documented better, IMHO.

Agreed, I believe there should be a section about legends in the Customizing Plots user guide. A PR to add that would be greatly appreciated, it should also cover the legend_offset parameter which does allow adjusting the legend in screen space.

I'd be happy to submit a PR, but I don't know how legends work. A bit of a catch-22 😅

For those landing here after googling for this, the position of the legend can be set with .opts(legend_position='top_left') for example.
