John Beard 7acc0b89f9 Pcbnew: fix 45-degree snapping of ruler and dimension tools ...

This introduces a new util function in geometry_utils which snaps a vector
to axes or 45 degree lines. This can be used whenever you want to
snap a vector to these angles, but still want it to stay on a grid.

This snapping is used for the dimension tool and the ruler tool.

This is substantially simpler for two-point tools that the method
used by the line tool, which uses DIRECTION_45.
